Muffler so hot it's melting the carpet in backseat

Showing 6 out of 6 Posts
Question From nerno1 on Muffler so hot it's melting the carpet in backseat

1988 Gmc S15 4wd 4.3L V6, Vehicle was running rough at anything but idle, preformed complete tune up Cap, Rotor, Plugs, Wires. Changed all Filters on the vehicle at this time also. This action made matters worse? checked Timing which is correct to engine decal label, 0 Degress BTDC (California vehicle). Thought was not getting enough exhaust exiting tail pipe, ran by the local muffler shop, they put it on a lift pounded on the convetor (sounded like loose sand) Had the convertor replaced along with o2 sensor. Drove it home now the muffler is so hot its melted the carpet in the rear passenger seat??? and yes the muffler is in the area where the carpet is melted not the Convertor? Sujestions. Oh to top this no Codes came up using my code finder from pep boys.

Response From Sidom

Have to admit thats a strange one...... Since the convertor came apart I would be tempted to change the muffler, never know how much junk got caught up in it......... Usually the cat is the 1st thing to overheat....... If the rest of the exhaust isn't overheating & the engine is in fuel control, there really isn't too much else it could be................ Pound on it & see what it sounds like.........

Response From nerno1

As Dan D sujjested it can try disconnecting the muffler, before I do that, could you explain to me how to make sure the engine is in (Fuel Mode). Also how ( and I feel really dumb asking this) does one check the EGR system to see if it is working.

Bye the way thank you for your reply.

Response From Sidom Top Rated Answer

As far as fuel control goes you just want to make it's not running too rich or too lean. If your scanner has a data steam you can look at the fuel trims (probably called intergrator & block learn on that one) or make sure you are getting good crosscounts on the O2s.

I believe that is still using a vaccum EGR. To test that on you take off the vacuum line and apply vacuum from a pump the engine should idle down or die, if it doesn't then you have a plugged port or bad valve........

Dan has a good idea to drop the muffler, if the problem is gone & you like the way it sounds......problem solved...

Response From DanD

Considering that the converter is new; it should be relatively easy, to drop the extension pipe off the back of the converter. Take the truck for a road test and see if the running issues are gone.

Dan.

Response From nerno1

Thanks Dan,
I will give it a try.

1984 GMC Pickup Backfires

Question From Gmconyx on 1984 GMC Pickup Backfires

1984 GMC Pickup backfires when i left off the gas on the freeway. Even in my driveway the pickup backfire when i rev it up. It backfires so bad that my catalitic converter blew.

Response From PTEC

explain to me what is a backfire and how can you tell if it is a backfire, then i will see what i can do for you.

Response From Gmconyx Top Rated Answer

The truck backfired and blew the catalitic converter and the muffler expanded them. The sound that the truck makes is that of a canon going off. On the freeway, when I let go of the gas you can hear a big boom and feel like a big firecracker just blew under your ass.

Response From black bear

if you have a large enough exhaust leak it will back fire

Response From steve01832

Start with a compression test across the board. If it is low on all cylinders, check the timing chain to see if it jumped or has excessive slack in it. If your vehicle has an air pump and it is operational, make sure the solenoid is diverting the air in closed loop. If it is sending the air downstream you will have the makings for heavy combustion in the converter. One way to check this is to pinch off the hose at the air pump that goes to the converter and drive the truck. If the backfire stops, you know which system has failed. Good luck and keep us posted on what you find.

Strange - oxy sensor maybe?

Showing 2 out of 11 Posts | Show 9 Hidden Posts
Question From belliott on Strange - oxy sensor maybe?

Just finished a complete exhaust job on my 1993 GMC 3500 with a 350 and AT. Replaced everything from the manifold back including the oxygen sensor before the cat. covt. Now she won't start and is choking black smoke while trying to start! This was only a exhaust job and she ran fine before -- any ideas-- has the new oxy sensor fried my computer??

Response From Tom Greenleaf

That is strange!!

Why did you replace the o2 sensor?

Any chance if you used torches that some wiring got messed up?

Just a thought. Anybody else have ideas here? T

Response From belliott

no flames - just unbolted and dropped the old. Old sensor had welded itself with rust to old pipe so a new one was only $18.

Response From steve01832

Unplug the O2 sensor. With a digital multimeter, set volt scale to 12vdc. Turn key on engine off and test O2 sensor plug on vehicle side. If you have approx. 1/2v the computer is fine. I'm assuming this is a single wire O2 sensor. Computers look only at the O2 sensor voltage after the engine is at operating temp. It shouldn't affect a cold start. My question is "Did you use a welder when you did the exhaust or was it slip on with clamp)? A mig welder can send high voltage back on the vehicle frame and can spike a computer if you leave the battery connected! OOPS

Response From belliott

no it was a slip on with clamps. no electrical charge at all because the battery had been disconnected before I worked on it

Response From steve01832 Top Rated Answer

Can you hear the fuel pump run when you turn the key on? Is it possible the harness got yanked by a pipe or muffler during tear out?

Response From belliott

Yes that why this is so puzzling - I took the exhaust off and disconnected the o2 sensor and she still won't start and is choking on black smoke like incomplete burning of fuel.

Response From steve01832

Can you smell fuel if you crank the engine for about 20 seconds? If you can, let's check for spark at a plug wire.

Response From belliott

Yes, she's trying to start but she can't catch her breath! It's a throttle body injection and the only thing I can think of is the timing is out of sync or the computer is behind or ahead in it firing order???

Response From steve01832

Did you confirm spark?

Response From belliott

Not yet - I'll have to get back to you because I'm away for the truck right now -- I will check the dist cap also maybe it's cracked-- thanks for your time

electronic shift transmission help

Showing 2 out of 14 Posts | Show 12 Hidden Posts
Question From mtgeorge741 on electronic shift transmission help

i have a 1996 gmc jimmy with 4.3l engine and the transmission is an electronic shift transmission. think the 4L60. 123k miles. there is delayed shifting going on. it's acting like it doesn't want to grab the higher gear. there is a slight delay in when putting it into reverse. thinking maybe some sort of sensor on or in the transmission but don't know which one. need help asap

Response From Racer 51

I don't know the TSB # (Technical Service Bulletin) but I know there are TSB'S out. Check with a dealer for the TSB'S. Post any error codes that are set so they can be seen.

Response From mtgeorge741

that doesn't help

Response From Discretesignals

How is the fluid level and fluid condition?

Reverse is all mechanical and not computer controlled. If you have a delay going into reverse, there is a pressure problem inside the transmission. You'll have to connect a transmission pressure gauge up and do some line pressure checks.

Response From mtgeorge741

condition is good. level is lower than it was n white smoke from exhaust consistant with tranny fluid burning but dont see any lines as should between the two. i don't see the shift linkage, nothing on the transmission. just a wire going to a large sensor on the side. dont see a kickback, a modulator, nothing. there are no vacuum lines going to the transmission

Response From Discretesignals

The transmission line pressure is controlled by an electrical solenoid called a PCS (pressure control solenoid), so there is no throttle valve cable or vacuum modulator. Can't think of any reason the engine would be burning transmission fluid. Is the white smoke coming out from the end of the exhaust pipe or is it coming from underneath the vehicle?

Response From mtgeorge741

and where is that located? the exhaust pipe

Response From Discretesignals Top Rated Answer

The end of the exhaust pipe is at the back of vehicle. Unless the muffler fell off...

Response From mtgeorge741

i meant the pcs. i know where the exhaust is.

Response From Discretesignals

The PCS is on the valve body behind the transmission pan. PCS won't cause a loss of fluid though.

Response From mtgeorge741

is there wires going to it? is it grey in color?

Response From Discretesignals

The wires to the PCS solenoid come into the transmission at the electrical plug you saw on the side of the transmission. The PCS gets power and ground on the light blue/white and red/black wires at the plug.

The electrical harness inside transmission that comes from the other side of the plug that goes to the solenoid itself use a light blue and a purple wire.

Response From mtgeorge741

okay. you'd think that would throw an engine code. when i ran the codes before, nothing showed up about the transmission. just oxygen sensor no circuit, another oxygen sensor code, multiple misfire, cylinder 4 misfire. how do i adjust the shift linkage?

Response From Discretesignals

If the engine has misfires and or problems, you need to correct those first. A bad running engine is going to affect the operation of the transmission. Once you have the engine problem sorted out and you find you still have a problem with the transmission is when you need to take it into a transmission shop and have them take a look at it. They might do some pressure tests and see what line pressure is at when the reverse delay is occurring. It would also be important to find out where the transmission fluid is leaking from.

improving mileage?

Question From maelstrom on improving mileage?

just wondering if anyone could tell me what i can do to improve the mileage im getting? the vehicle is a 1993 gmc sierra 1500 sle with a v8 5.7l engine with 2wd not 4x4 that has 240000kms on it. i know a tune up is due on it, but was wondering what else would work

Response From Tom Greenleaf

Wasn't meant for gas mileage but some basics: Tire pressure to suggested pressure. Unload unnecessary stuff. If highway use just slow down some can help but there's no magic out there to make it do tons better. Good air filter can help too along with being in general good tune,

T

Response From re-tired Top Rated Answer

As Tom said , do the basics and common sense stuff, like accelerating easy anticipating stops, drive as smoothly as possible .You will be suprised how much it helps . Stay away from the gimicks , Fancy induction systems , super duper mufflers, chemical additives, a bottle of injector cleaner now and then is ok . Magnets on fuel lines , etc, The only gain will be the sellers profits.
