1984 toyota stalling

Showing 4 out of 4 Posts
Question From ryano5x5 on 1984 toyota stalling

My 1984 toyota pickup 4wd with the cabureted 22r 4 cylinder engine will start, run, and idle fine. The problem is that when the engine reaches a certain load threshold it stalls. This happens while on the road at speeds that vary depending on conditions, but usually around 45-60 MPH. In order to fix this issue I have replaced the fuel pump, the fuel filter, all vacuum hoses, the carburetor, the radiator, the ignition control module, the catalytic converter, the ignition coil, and the power steering pump. I have tested the pressure on the EGR valve and the EGR vacuum modulator, tested the distributor diaphragm, and performed a complete tune-up including new plugs, wires, distributor cap, rotor and timing.

I am at a loss as to why this vehicle would still be stalling while driving when it reaches a certain load threshold, and have no idea where to go from here.

Response From Discretesignals

Does it sputter, backfire, bog out, or just shut off when the problem shows up? Does it restart right after it stalls?

Response From ryano5x5

Nothing signals the stall, I am driving down the road and the engine just dies. Since the engine is running and it is in gear, it starts right back up when I let off the foot-feed. Sometimes if I do not have the accelerator pressed down enough the vehicle bucks while it is stalling and restarting, but releasing the foot-feed solves that problem and it starts.

Response From Discretesignals Top Rated Answer

I believe there is a sight glass on the carb to view the level of fuel in the carb bowl. Next time it stalls, instantly turn off the ignition (not to the steering lock position) and push in the clutch so the engine doesn't spin. Then look at the level of the fuel in the bowl through the glass and see if it is at the right level.

egr cold start

Showing 3 out of 20 Posts | Show 17 Hidden Posts
Question From chas on egr cold start

when i start my car cold the EGR system and vsv is open.
as the temp rises it closes then opens under load or throttle up.
is it correct for the EGR system and vsv vacuum open on cold starts?

Response From Hammer Time

Is this a Ferrari or a lawnmower?

You should know how it works. YEAR? MAKE? MODEL? ENGINE SIZE?

Response From chas

yes, i know how it works.
it functions but vacuum is on when cold start.
should it not be closed on cold start?
all EGRs and vsv work the same, no?
as an experiment i did this.

with engine stone cold.
1. open hood
2. turn key to "on" with panels lights for oil and CEL on. did not start it up.
3. go back around to front. disconnect vacuum line out from the vsv at the vacuum rail to EGR and modulator.
3. draw through it with my mouth. vacuum was open through the vsv. i could draw through the vsv
4. removed the plugin to the vsv.
5. draw on the vacuum line again with my mouth. vsv vacuum was closed. could not draw through the vsv.
6. plugged the vsv plugin back in. it opened. could draw through it again.
this test was done stone cold.

when at running temp i removed the vacuum line again from the out port to the EGR and modulator.
at idle it is closed.
when i rev it a little i put my mouth on the vsv outport. it opens. i can draw through it. then closes as it returns to idle. could not draw through it.
when it warms up a little the vsv opens and closes and seems to function normal.
is this normal?
is the vsv vacuum and EGR supposed to be a closed circuit on cold start?
thanks H.

94 toyota pickup 22re.

Response From Hammer Time

When I said you know how this works I was referring to the forum and your lack of vehicle information but now that you have expanded, no, you do not understand how this works and no, they do not all work the same.
If this is all still hooked up properly it will work the way it was designed. The valve is open because it is supplying a bypass for the vacuum back to the manifold and when it closes, it basically forces vacuum to the EGR valve.

All this is assuming that this is Federal/Canadian emissions and not California.

Response From Tom Greenleaf

Is the truck and this engine running properly now and you just stumbled on this somehow?


Being a Toyota especially (others too) are good at custom engineering specs for these things for the destination they will be sold (or expected to be) as well any vehicle makes does.


General on EGR times to operate would be less to none cold and at idle and none again at full throttle. Exactly what temp and load on engine would vary. If not running properly and you think this is the reason I would have to buy some real detailed info for the specific engine sold to where with what specs.


What is the problem you are having if any?

chuck>>>>
the EGR had a problem.
the EGR VSV was bad and had a few bad vsv plugins on the vsvs'...the vsv plugins were worn out and broken wires at the plug to the vsv.
i got some good ones in good condition.
wired them in taking note of which wire on the harness goes on top and bottom to the harness.
the EGR vsv still did not work.
i switched the wiring polarity on the EGR vsv plugin.
now it worked. i guess the polarity was backwards. bthuom how i got it wrong.
but i still suspected a problem because the EGR vsv vacuum is on when cold start.
Hammer said all is good so i guess ill leave it alone.
any more suggestions Tom?
is it working proper?

ever since the conceptiion of the car it became a source of polution.
in the turn of the century in the early 1900s that were not many cars on the road.
as the population grew and more cars on the road.
air polution became a problem.
also get rid of leaded gas and TEL

and i think there was another called MSB?
they were all poison


im all for clean air.
alot are to young to remember way back in the 60s and 70s what it was like.
the air was terrible.
there was a dark grey almost black muck in air.
my eyes watered and chocking on the bad air.
the air is much better now.

why did you delete that link?
whaddya mean not allowed?
this is part of the history of the car and why things are the way they are.
i lived through it too.
put it back please.

Response From Discretesignals

If this is CA emissions, it probably has a VSV for EGR. I do know that Toyota VSVs will not be activated by the engine computer unless the ECU sees vehicle speed.

I usually T in a vacuum gauge into the hose that goes to the EGR valve and drive the vehicle. When the engine is warmed up, you should see 5-7 inches when you accelerate.

DiscreetSignals>>>>>I'm looking at the diagram above and the VSV has nothing to do the the EGR system. Maybe it is the wrong diagram or something. The VSV according to the diagram is used for the pulse air injection reaction valve.
Thermal vacuum valve should be closed when the engine is cold, so vacuum can't reach the valve. EGR valve should never ever be open at idle.

chuck>>>>>it is a CA model. i usedd the vacuum diagram under the hood for CA.....i think the diagram is ok or close. this 1994 CA model does have 2 vsv in the EGR system and does have a PAIR valve. the first vsv is the one im looking at because it's open on a cold start. the EGR should be closed when cold start or idle.

the vsv is open on cold start then closes after it warms a little then seems to function normal at operating temp.
im pretty sure the EGR vsv is supposed to be closed on cold starts and at idle. it's supposed to open when throttle up under load.

is it possible the vsv plugin is wired backwards? is there a + - polarity or dont matter how it is wired with the 2 wires in the vsv plugin?

Response From Hammer Time

Question answered multiple time.

Closed now

Response From Hammer Time

One more time I will tell you how this works and then I'm going to close the question.

The valve bypasses the vacuum so it doesn't build up when open. When it closes, it seals off the vent and causes vacuum to reach the EGR. Thus, it is open when the EGR is not applied.

********************
chas: Going blind trying to read your script. Whatever the reason a device or knowing how to use it or a forum it lacks and is confusing everything


So far I can make out that nothing is wrong but you've found wires and a plug damaged to a VSV (Just a valve that opens and closes) that could be for assorted things for assorted reasons.


So - there's nothing about this that is really wrong except now a question that if wires were reversed polarity because of the damage you thought the could be so asked if that would matter. If just two wires to a plain switch I say it wouldn't matter, especially for model year 1994.


It's thought to be a CA vehicle and that does change things. Sticker under the hood if you believe it's original to the truck (might not be at all) should match other info and VIN# around the truck which also identifies what it was when new.


OK: In these years and before as well vehicles did put diagrams on stickers under the hood for common info as well. Tons of repair manuals would default to suggest going by any info under the hood over theirs.


You have rewired and a good used plug I understand one thing you found and continue to wonder if it should be open or closed and when and have been told that in this thread so unless you have a problem why are we dragging on this thread over something that isn't broken?


chas: Some suggestions for used plugs, wiring pig tails when needed especially when not available new with original colors match them up with the used item and your own vehicle as best you can.


Are we all done with this now?

Response From Hammer Time

Here's a different diagram.

The valve stays open and vents vacuum back to vacuum. When the valve is closed it allows vacuum to build and then open the valve. It works opposite of other valves.


Response From Hammer Time

I guess it's time you read the rules.

Saw some of just the garble saying LEAD in fuel and TEL is the same thing BTW "TetraEthylLead" was the product used to make cheaper low octane fuel have the "anti-knock" rating of same fuel without cheaper than using more % of real crude oil to make it. Lived all thru all that mess and politics of it. Was a real problem upon introduction no longer a single thread about a lead contaminated fuel issue on this site that I can recall and was a routine problem back when.


Gotta go - sorry - will read the rest quite a bit later,

ok, so the vsv vacuum is supposed to be open on this model vehicle when stone cold?
its a calif car.
i used the the vacuum hose diagram under the hood for CA.
i was not sure if the EGR and vsv was working proper on cold start.

Response From Hammer Time

Yes, closing it applies EGR vacuum if the vacuum modulator allows it.

Response From chas

H, i dont think were on the same page.
is the vsv vacuum and EGR supposed to be open or closed when cold start on the toyo pickup 22re?

Response From Hammer Time

Yes







PURPOSE
The exhaust gas recirculation (EGR) Valve is a vacuum operated valve which opens and closes a passage from the exhaust manifold to the intake manifold. This allows flame temperature in the combustion chamber to be lowered by diluting the incoming mixture with exhaust gases limiting the formation of nitrous oxides (NOx) .

OPERATION
At specific times determined by the Thewrmal vacuum valve (TVV) the EGR Valve opens and allows exhaust gas to flow to the intake manifold. The amount of exhaust gas introduced to the intake system is directly relative to pressure in the exhaust system.


PURPOSE
The exhaust gas recirculation (EGR) Vacuum switching valve (VSV) controls the regulated vacuum applied to the EGR valve. The Engine Control Module(ECM) uses the VSV to prevent EGR operation when the engine is cold to improve driveability.

OPERATION
The VSV receives voltage whenever the ignition switch is turned on. When EGR is required, the ECM grounds the remaining terminal which opens the VSV vacuum passage allowing vacuum to the EGR valve.

Question From tjmaxxx on toyota camry shut off when braking for stop idle seem good

I HAVE 1993 TOYOTA CAMRY. REPLACED THE ENGINE WITH A 1995 TOYOTA CAMRY EVERYTHING HOOKS UP FINE IDLE GOOD. IT SHUT OFF WHEN SLOWING DOWN TO STOP MOSTLY AT STOP SIGN AND TRAFFIC LIGHT. ALMOST AT EVERY STOP UNLESS I HOLD BRAKE AND GAS PEDAL AT THE SAME TIME. SEVERAL DIFFERENT MECHANIC TRACED EACH OTHER WORK AND FOUND NOTHING AS FOR ENGINE CONNECTION. THE CAR WAS PLACED ON A DIAGNOSTIC MACHINE FOUND NOTHING. NO ENGINE OR WARNING LIGHT ON. NO ERROR CODE.
I JUST WONDER IF THE 1995 ENGINE IS TO HIGHER MODEL FOR THE 1993 CAMRY. OR DO I NEED TO CHANGE SOMETHING ELSE LIKE DISTRIBUTOR OR THE COMPUTER UNIT. PLEASE HELP. THE IS WAS A USED MOTOR PUT IN. MAYBE IT A 1996 ENGINE
2200 ENGINE

First check for any possible vacuum leaks and for a stuck open EGR valve. If you eliminate those things, you may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

when in park, try pumping the brakes. Does this make it try to stall when doing it? If so you have a bad brake booster

2000 TOYOTA 4RUNNER NOX TOO HIGH

Question From birdthe3rd on 2000 TOYOTA 4RUNNER NOX TOO HIGH

Trying to get a 2000 3.4l Toyota 4Runner to pass emission. The limit reading of NOX is 2.00. The reading the 4runner is producing in 6.34 befor a new cat, and 6.65 after replacing the cat. All the other ( HC, CO, and CO2) readings are with in spec with or without the new cat. Befor trying the new cat, was told to try some e85 fuel mixed with what was in the tank all ready. Can anybody lead me in the right direction.

Readings befor the new cat. Readings with the new cat.

Actual Limits Actual Limits
HC .4422 1.2 HC .2907 1.2
CO .6588 15.00 CO .1106 15.00
CO2 439.23 ...... CO2 444.35 .......
NOX 6.34 2.000 NOX 6.63 2.000

Response From Hammer Time Top Rated Answer

You just wasted money on that stuff. NOX is a byproduct of high combustion temperatures. To lower NOX you have to lower the combustion chamber temp. That is the main job of the EGR valve so make sure that is working properly and not restricted. Next you want to look at thermostats and engine temps, maybe even ignition timing if it's adjustable.

vacuum-like noise only when accelerating

Question From zink08 on vacuum-like noise only when accelerating

I hear a vacuum-like noise under the hood of my 97 Toyota Tacoma (2.4L, 163k miles) only when accelerating. When I shift, the noise dies until I speed up for a second or 2. I noticed cracked hoses connected to my PWM valve sensor, cut the tips, re-attached them, and added electrical tape and plastic ties. The noise was gone completely for about a day, then came back. It sounds to me like the noise is now coming from around the engine, as opposed to around the PWM sensor at the periphery.

About 6 months ago I had a check engine code for excessive flow through the EGR valve, but it went off within a few days.

Since I currently have no check engine light and no problems idling, could the EGR valve be to blame? Should I just change the hoses anyway? Because I don't hear the noise at idle, would it be worth spraying the throttle body/intake manifold with carb cleaner, or would I likely not hear it anyway?

Response From Tom Greenleaf Top Rated Answer

Spraying carb cleaner may find a vacuum leak. If the hoses were that bad they should have been replaced. EGR is enabled via vacuum and told when to open depending on how much is sensed. A leak will mess several items to be fooled.

Make sure air cleaner assembly is all well installed and intact too,
