Question From amerbgd on 1993 Mercury Villager 3.0 shuts down

First of all the car hasn't been driven for a month and a half. Before that it has been driven for a month. Before that it has been driven about a mile every 2-3 weeks. I havent had these problems even when i haven't driven the car for several months.

Whenever i break a bit harder at stoplights it turns off. I checked the battery cables they are held on the battery tightly.

Response From autojoe

check the brake booster vacuum line for a leak or bad connection.Any rough idle?

Response From amerbgd Top Rated Answer

very rough idle the whole car shakes but i also have a broken bolt that holds the exhaust manifold to the block. how do i find the brake booster line?

Response From autojoe

its behind the master cylinder at firewall.the master cylinder is attached to it.

Response From amerbgd

just threw a look the front side of the cylindar and lines are dry and clean looked at the pavment under the car all dry. I drove it for 15min about 5 hours ago. If the cylindar is the problem is it possible to lose my brakes totally while driving?

Response From autojoe

it does not hold fluid.......it passes air through line.check for any cracks and make sure all connections are tight and no play in them.take some dish soap in water and put some around connections and with running see if any bubbles.the exhaust leak causing back pressure could cause you problems.

Response From autojoe

with engine off pump brake pedal 4-5 times and hold....the pedal should hold steady.....now still holding pedla firm start vehicle and pedal should drop to a point and then hold steady.

working with vacuum gauge

Question From zoggnoff on working with vacuum gauge

I can't seem to figure this thing out.
The only reading I could get off the gauge was when I took the PCV valve off and shoved the tapered end fitting into the pcv line, it read 13 in.
Not sure if I had the intake manifold vacuum line, is it the line that connects to the air assembly duct?? because that was 0 in.
and I can't find the EGR at all.

This book gives me one picture, sometimes no picture at all.

it's an 03 eclipse v6 3.0L

Response From Tom Greenleaf Top Rated Answer

Vacuum gauge is an excellent diagnostic tool. Not sure if PCV gets true "Manifold Actual Pressure" (meaning vacuum) or not. A pwr brake booster should! Best to use a "T" so the device still is enabled.

FYI: Atmosphere is 14.7 PSI at sea level. Vacuum gauges are measuring "inches of mercury or HGs" so not the same math. At sea level you see the full # which if perfect is 29.92 Hg. Engine vacuum at sea level should be around 18 or so and with a rev show over 20 then be stable again.

You can deduct ONE Hg per 1,000 feet of elevation.

Hope that helped??

What is your elevation? Google Earth will tell you by the foot! I'm at 232' for example!
T

Response From zoggnoff

google earth puts me at elev 9ft

Response From Tom Greenleaf

Consider that true readings or "Sea Level" for any use of the device. I do at under 1,000 which is most of the populated world. The day's atmospheric pressure has an impact as well. Once in a while someone will ask me about some #s and live at "mile high" Denver, CO or even higher!

Just for fun - heard that aircraft sets cabin pressure as if you were at up to 10,000 ft and hope you aren't working on a car in the plane but it clearly has a different feel to it to me anyway and air is drier.

Vacuum is a great tool as said for auto engines and air conditioning of course. Look for steady needle (valves good) - drifting needle (a gasket leak) - consistently low - (valve timing off perhaps) -- there's lots.

Learn where to check such that it's "actual" vacuum and not "venturi" vacuum.

Vacuum can tell of an exhaust restriction as well!

Response From zoggnoff

I've been sick for 4 days now. I was in the middle of doing this test when I saw the news today.
wow.

moving on though. The test results were 14 in
bobbled between 12 and 14 in as the idle bobbled between 800 and 1100 rpms

dropped even lower when I unplugged the pcv valve but then the idle speeds up and the in Hg go back up
could this be a vac leak?
if so i'd like to replace all the vac lines, where can i buy new vac lines?
are they all the same size?
they seem to be nearly the same to me

Response From zoggnoff

also according to the multimeter i used on the TPS it went from 0.2 to 4.8
supposed to be 3.5 to 6.5 k when moving the throttle while hooked up to the meter.

could this be the source of all these damn problems?

Response From Loren Champlain Sr

zoggnoff; You should be seeing 17-19hG at idle. As Tom suggested, 'T' into the vacuum booster line or find a manifold vacuum hose. If your vacuum is lower than it should be, it could be caused by poor running condition. Retarded timing, overfueling, misfiring, ect. The TPS voltage wouldn't come into play, at idle. However, as you sweep the TPS with your multimeter, watch for 'glitches'. If there are any, it should be replaced. Also, what kind of symptoms are you dealing with?

Response From zoggnoff

Not sure where the booster line is but I was able to get hold of a Factory Service Manual for my specific vehicle, much better pictures of where things are.
was able to pin point all the parts that eluded me before, also according to it the best place to T-in is between the fuel pressure regulator and the intake manifold plenum, which I found and T'd into. Had to trim some tube from my new gauge to make it possible but I was able to get a 14 in reading from it.
Stepping on the gas then letting off quickly went from 14 in hg quickly to 0 in hg then quickly to 25 in hg then slowly back to 14 in hg... but the RPMs drop very slow as well and settle at about 1100 RPMS.
figured it should have dropped quickly in park but didn't.

My symptoms are rough somewhat irradic and sometimes high idle and low vacuum.
the oil leaks and the car smells bad sometimes.
had to recently replace the IAC because it was rough like this before, but instead of idling high it would just stall and the IAC eventually stuck closed and tested dead.

Im affraid that under whatever stress that is going on under the hood that this new part may soon be tossed into the trash with the old one.
part was hella-expensive

What should i do?

Response From Tom Greenleaf

Rough idle and 14 reading - not right. What vehicle and engine are we talking about and how many miles?

T

Response From zoggnoff

2003 mitsubishi eclipse gt
v6 3.0L
133,000 miles

Response From Tom Greenleaf

The fact that it could do that snap to 25 is good. Rough idle will not give you a steady, dependable reading but normally would be 17-19 as Loren said.

It's one tool in tool box. Need to chase down the rough idle now - manifold vacuum leaks, tune up items etc,

T

Response From zoggnoff

Just got in the mail, vacuum pump/brake bleed kit so i can check the EGR & solenoid among other things.
too late in the day to use it now but I did spray carb spray all over the throttle body where it butted up to the manifold and there was no change in idle.
sprayed the manifold itself too but i'm not familiar with that part of the engine so i may not have sprayed the right spots but i did try to spray everything on it that wasn't rubber or plastic because i now the solvent destroys those materials. still no change in the idle.

if it's not the manifold leaking and if I replace all the vacuum hoses and if the EGR and solenoid pass a vac test could it be the spark plugs and or wires, rotor and cap? the plugs were replaced once but the engine has been running hot, very hot. I'd say for the better part of 2 years the engine would overheat until eventually the radiator blew a hole in the top and had to be replaced, still overheated, replaced the thermostat and problem with heat solved.

what steps should i be making?

Response From Loren Champlain Sr

zoggnoff; Check for a vacuum leak at the EGR valve, itself. Sometimes a chunk of carbon can get stuck between the pintle and seat. Be careful not to try and apply too much vacuum to the EGR as you could rupture the diaghragm. It may not hold vacuum if it is a backpressure type valve, so don't condemn it if it doesn't. EGRs are usually quite easy to remove and inspect. Once off, if nothing is visible, you can pour liquid in one side and see if leaks through. It shouldn't.

Response From Tom Greenleaf

Good one Loren. Pintle can be cleaned - push up and down on it with carb cleaner in the inlet side. Real good one will not leak out even thin viscosity of carb cleaner! You may be able to save gasket with high temp Permatex sealer.

Vacuum. That one I disagree with. Diaphragm should hold a hand held vacuum at max. If it ruptured at full vac it tisn't good IMO. Remember or know that atmosphere is only 14.7 psi that we live in. Expressed in "inches of mercury" max vacuum ism 29.92. Engines run on creating a vacuum to draw then compress vaporized fuel and air. Short of pushing air (turbo type/ram air stuff) the most the can get is the 14.7 in PSI and they don't ever show that. Said earlier by Loren engines will show 17-19 Hg at a smooth idle.

Pun intended - vacuum is a cool tool which sucks! Laugh!



T

Response From Loren Champlain Sr

Tom; Backpressure type EGR valves won't hold vacuum unless backpressure is present. Weird, I know. Don't ask me how it works.

Response From Tom Greenleaf

My only point was 100% vacuum is only 14.7 psi in reverse pressure. Any vacuum item that fails with just that probably tisn't any good.

Please understand we are all here to help and LEARN too! It's a never ending cycle to keep up with what parts do what and what they tolerate.

Old Pharts unite!

Response From Loren Champlain Sr

>>It's a never ending cycle to keep up with what parts do what and what they tolerate.

Old Pharts unite! <<
Oh, how very true! Didn't mean that thing about the backpressure EGR valve to be anything other than informative. Didn't know if you'd run into one before. Sorry if I stated it wrong.

Response From Tom Greenleaf

We (speaking of regulars) are here to help and we learn too! If any one of us thought they knew everything it's proof we don't!

The only failure is not trying. It's my opinion that any vehicle diaphragm will hold full vacuum. As to back pressures - that's a different problem/issue,

T

PS: Thought for the day. If you took a tire with 1lbs of true air into outer space or a complete vacuum it would read 14. something PSI! A tire at 35 psi would increase by the 14.7 - just examples from my out of space missions

Response From Loren Champlain Sr

>> If any one of us thought they knew everything it's proof we don't!

The only failure is not trying.<<
How True!!!! I'm trying to remember my emissions class...Were dealing with a GM EGR valve. With vacuum going to it, it wouldn't open unless it sensed exhaust backpressure and the diaghragm wouldn't hold vacuum unless the backpressure was present? On the other hand, that was back when I had a brain. Probably, 20yrs ago? Hopefully, one of the younger guys with some brain cells left will jump in here. LOL.

Response From Hammer Time

Feedback EGR valves are very common and you are correct, they won't hold vacuum unless they get exhaust pressure first.

Response From Tom Greenleaf

I'm good and confused. I can see that and EGR could be designed to sense pressure one way before activating vacuum to a diaphragm but don't understand if full vacuum it damaging??

T

Response From zoggnoff

book says 5-to-10 in-Hg vacuum to EGR valve with engine idle, if speed does not drop considerably (or stall) indicates possible faulty EGR valve, blocked or plugged EGR tube or passage in intake and exhaust manifolds may be plugged with carbon build-up.
EGR vavle unbolted apply 15 in-Hg vacuum, if stem moves it's good.

Picked up 3 spark plugs and some anti-seize compound for the front. I figure why not change the easiest plugs first, see if any changes, they were $2 a piece
had a random misfire code at idle again, cleared, didn't come back.

have not tested nor replaced parts yet (plugs included) still waiting for some tools to arrive

Response From Tom Greenleaf

Interim note: Watch out for anti-seize (alum stuff) - make sure on threads only - It can conduct electrical energy and mess us diagnostics.
T

Response From zoggnoff

changed the front three plugs, no effect on how it ran.
currently getting a p0401 code.
so definitely need to check the valve and stuff... but could that code just be a result of having a low vacuum reading of 14 in-hg?
engine was knocking.

I have some new silicone tubing on order to replace vacuum lines, will have soon, i figure once that arrives i will clean out the metal parts of the tubing on the vac system with wire pipe cleaner brush and some carb spray, also sometime on that day test the vac system integrity itself with the pump etc etc.

what do you think?

Response From carsinsc

Have you done a compression test on this motor? If it was overheated, you may have low compression causing your problems. A leak down test would help verify wether your valves are sealing properly. Start with the basics before you throw a bunch of money at a problem that can't be fixed by just replacing parts. Poor compression = poor running.

Response From Tom Greenleaf

carsinsc: This thread is well over a year old. Welcome to the site but take note of the dates of the threads,

Response From Hammer Time

It's not being damaged. The vacuum just get bypassed until the exhaust backpressure closes the vent.

Question From zerothenone on 1980 mercury monarch 1st gear only

1980
mercury
monarch
unknown size
50246 miles

car cant shift from first even at high rpm, sound of air coming out of what i think to believe is the carborator

Response From nickwarner

That sound is a vacuum leak. You need to find out where it is. Should be some vacuum line running to the trans and I'd be every inch of the 32 year old vacuum hoses on the whole car are shot. Get them all changed. You buy it in bulk at the parts store, get about 5 feet each of several sizes and do one at a time. Also, what is the fluid level at? If you move the shift selector manually will it go to the next gear?

Response From zerothenone

did not try the manual shift idea and the fluids are just below the top notch of the full line it just happened for the first time today as well so its new to me

Response From nickwarner

This car has done a lot of sitting in its life and both lot rot and vermin can do bad things to a car left sitting. Did you just recently buy the car? Do you know how long its been stored?

Response From zerothenone

ok i bought the car in june and it was sitting for some years yes but this is the first time it has happened

***update***
i forgot to mention a very important fact that when its idling it knocks like a deisil tractor

Response From nickwarner

when did it start doing that? Check the torque convertor nuts and make sure they aren't loose. Oil level good? I'm guessing this has an idiot light and not a gauge, may need to verify true pressure with a gauge.

Response From zerothenone

yes it does have idiot lights and all levels are good im taking it to a shop tomorrow im in way over my head

Response From Tom Greenleaf Top Rated Answer

I think this is a very late carry over of some older designs for trans shifting. A vacuum tube goes to a modulator (vacuum operated) at transmission and the diaphragm itself can fail or anything that causes it not to get vacuum of actual manifold vacuum will force it to default to lowest gear for the speed the car is going. First could hang on till it reached about 45 MPH same as if gas pedal was floored for full power.

You hear it so it's leaking down more than just messing with the trans shifting but idle is probably so low oil pressure isn't keeping up which would be noisy. It's harmful. Nick is right on - dump all vacuum hose you can find. It's cheap but should be done one at a time as there isn't any color coding or what goes where info that is that exact.

Other vacuum leaks are carb to manifold, brake booster, a can that probably looks like a large painted soup can on an inner fender, intake manifold to head(s) was not a problem in the V8 (302 C.I.D.) but could be if a 250 straight six which would probably be the only two engines available.

If this is a VV carb virtually all of them were tossed out for another type as I don't recall one of those working well new and on warranty. VV = "variable venturi" and would show two black (?) funky things where a choke plate would be up top of carb,

T

Response From zerothenone

well its fixed now it was the relay for the hoses an end seemed to have popped off so they just plugged the hosses together and it works again

Response From Tom Greenleaf

Great - do toss all those hoses for automotive grade new when you can. May take some time but not that expensive on materials as said,

Odd Sound Coming from TXV or Evaporator

Showing 2 out of 11 Posts | Show 9 Hidden Posts
Question From dw8 on Odd Sound Coming from TXV or Evaporator

1994 Dodge Caravan SE, 3.3L, 98,000

I'm getting an odd sound in the passenger compartment (which appears to originate from the center dash area) ONLY when the A/C is on and the car is accelerating.
The sound can not be heard in the engine compartment.
At idle the sound is NOT heard NOR does the sound occur with just heat or blower only on.
I'm getting between 42 and 52 out of the A/C depending on ambient.
This has been going on for some time.
Last time I put gauges on they meet specs.

Before I recover the Refigerant, Vacuum and Recharge, anyone have any ideas what is causing this and whether a recharge will solve the problem?

Response From Double J

Just saw your post in the other thread ....

This bulletin applies if yours has the Expansion Valve with part # 4677203
But as of 3/94 production date, they changed to the new part # 4766334
If yours has that then this doesn't apply....

Response From dw8

Thanks for Reply:

I do have part # 4677203 per the TSB.
Interesting that it worked fine for a number of years but last 3 or 4 is when the sound started.
I also have the same problem I replied to with the gentleman with the 2007 Grand Carava-- that is -- the AC cuts out from the center vents and is redirected to the defost vents when extra power needed (climbing a hill).
I've tested the check value (canister) -- mine attached to brake booster -- and holds 8 Hg of vacuum as chec k value designed.
Have NOT set up a test jig to try and check all door accurators, but all buttons appear to function as designed and direct air accordingly.

Question:
1) Think the two issues are related or independent?
2) Know whether Dodge built in some kind of AC cutout in the PCM when extra power needed and air redirection is just Normal?

Thanks
David

NO! That's not for extra power it's from loss of vacuum somewhere maybe not where you tested. Engines under load have no vacuum to supply so it's stored in a ball or can with a check valve in line for hold items where they were when no vacuum exists like asking for full or more power. For that they might (or some will add) a cut out for compressor under WOT = wide open throttle situations for max power.


Just to clarify just that,


T

Response From dw8

Mr. Greenleaf: Thanks for staying with me on this.


Engines under load have no vacuum
Agree that at idle max vac, as load increases vac decreases.

From what I can see the brake booster is the can as check valve connects directly to it.
From check value vac supply runs throught firewall to whereever -- most probably the A/C heater control assembly.

Unless the A/C heater control assembly is leaking somehow, you would think that if a button is pushed
which should redirect the vacuum to whatever door actuator, then climbing a hill would not cause air to be redirected to defrost.
ONly other things I can think of are:
1) the door is Not closing off completely and the air is bypassing it and consequently getting a redirect to defrost..
But if this is the case air should be coming out of defrost at all times.
2) When climbing the vacuum is dropping so low, that this is causing the blend door to close or close partially which
would then cause the air to be redirected -- defrost in this case.

Since the check values tests OK -- put a hand vacuum pump on it at 8Hg for 10 minutes and no leak down -- any idea how to troubleshoot this?

Response From Tom Greenleaf

In a hurry somewhat - sorry. Vacuum booster will be on its own for all safety reasons. Other vacuum controlled anything (includes many mode control actuators for heat, A/C vents or blend controls on some vehicles) uses the storage ball or can. Ball I think on this AND a check valve. You know it works if engine is off the next day or even 5 minutes it should change modes with ignition on and engine off at least once. If not it leaks somewhere. Most common is under hood plastic line looks like wire. At first it has to have a crack or maybe melted spot till you get nothing than it will only put air out defrost as the default mode when things fail.


Your reading of just 8Hg (inches of mercury) is low. Engines spike vacuum upon deceleration, idle should be around 18+/-. While driving along it will be all over the place with assorted loads and hold the max it got in that storage can/ball.


This being now 21 years old is more likely to use more vacuum things that very new. Any leaks to the source intake manifold actual pressure will lower your reading but also run like crap but it isn't bad enough.


This could also be what you are hearing! Listen for it. No telling what a split vacuum something might do for a sound? Age and all still more likely under the hood.


Hard to think a TSB this late just decided to show up now but could have.


Back to work for me. Go listen for a leak in a line going thru firewall. Wiggle test might really show you which one. It's ok if you find plastic line to razor cut and splice in windshield washer size common hose over the bad part. Wire cutters can pinch plastic vacuum line and seal it closed. Good luck. I think that's your noise,

Only check I've found in engine area is the one on the brake booster.
Will have to remove center console to see if another one on same line in passenger compartment.

FWIW There are two lines in the engine compartment.
The vac supply going from -- brake booster > check value > firewall > inside cab (assume to AC heat control assembly)
Line from cab > firewall > Heat Control Value (this value turns off the coolant running to the heater core).


You know it works if engine is off the next day or even 5 minutes it should change modes with ignition on and engine off at least once. If not it leaks somewhere.
Great TIP. Will check it out.


Your reading of just 8Hg (inches of mercury) is low.
8 Hg is per Shop. I just had a hand vac without going to the trouble to set up a constant vac at 8 Hg to test each system component - hence the test of just the check value at this point.


Hard to think a TSB this late just decided to show up now but could have.



My thoughts too, that's why I asked.

Thanks for all your input.

=========================

Now to pull dash whichis a #$%^@ on this vehicle.

Response From Tom Greenleaf

OK - if vacuum is regulated to only 8Hg than so be it. That item could leak too.


Why are you pulling dash? Yes it's a total pest on most everything but be sure you need to,


T

Response From dw8

FWIW:

Used my hand vacuum pump and tested vacuum lines.
Everything appears to be OK vacuum wise.
There is a water value that controls flow to the heater.
Interestingly, per shop - if I am reading manual correctly (don't know how to upload pics for a second opinion) - the water valuve is only shut off in "A/C recirculation" mode.
Also interestingly, is when climbing a hill in A/C recirculation mode, no air is diverted from other vents to defrost.

Still have noise and when / if find the solution will post.

Response From Tom Greenleaf

There's your clue! Look at that water valve and see if it's also actuated by vacuum. Truth is that is either to delay heater blower or adjust flow volume for heater temp setting but the choice of recirc vs fresh air is yet another diverter door quite possibly run by vacuum also - just don't know every vehicle's way without a hunt.


So if that put the mode door (panel, floor, defrost or mixes thereof) all set then the leak is to do with that.
This just smacks of a leak of vacuum not yet broken entirely plus the noise could explain both. Reading if true of 8Hg could have meant 18 Hg or be because of the leak and not enough while leaking. BTW - vacuum available while running will vary from zero to spikes up to maybe 22 or more when engine is braking vehicle as in down hill. Doesn't matter the storage ball idea covers all that normally.


This is somewhat common especially with plastic (but rubber too) failures anywhere the integrity of vacuum is compromised. Usually near something that moves or in the way of something that you might touch to do something else plus if touching something hot they can melt a total hole now partial.


Again those plastic lines look a lot like wire but end up with rubber ends or elbows as needed.


More: If this is at the control head inside, diaphragms inside or hoses involved it will be a pest to be sure, worse if control head itself is plain worn IMO. Had those apart and wonder why some last for crap.


You may find multiple vacuum connectors here and there of rubber and a way to fasten that's either loose or broken too.


I really hope you can create the noise and find it by listening. Try tricks like using a long snouted funnel, plain stretch of hose might do, Once found the fix should be clearer what it will take.


Oh - for pics try using a hosting site like photobucket or tinypics is another. Link to the pic or try if it will show directly via copy/paste or whatever your device's way is,

Response From Double J

Get a copy of TSB 24-12-94

Sounds like the condition you describe.


Here is an excerpt.....

Symptom/ Condition:

Under certain conditions, the internal flow of R134a refrigerant may set up a resonance in some evaporator cores.
This resonance can emit from the dash area as a high -pitched whistle noise. The whistle noise usually lasts 3-5 seconds and starts shortly after the A/C Compressor clutch engages. The duration and intensity of the whistle noise may vary as well as be highly intermittent. The whistle noise is most likely to be experienced at ambient temperatures above 85 degrees F and engine speeds around 2000 rpm.
