Hi

I think your first port of call here is to have the fuel pressure checked out, because it sounds to me as though you may have a faulty fuel pump or fuel pressure regulator.

You could have someone gently clamp the fuel return line to slightly restrict the fuel return and see if that makes any difference, but obviously this would just be a diagnostic measure and not a repair.

Regards

    After-thought!!



    There is also a possibility that the car may only be running on 2 cylinders and it may be worth also having someone check for sparks.

What is the most common cat oolitic converter that goes on the Avenger there is one on the manifold one at the base of the y pipe and one in midstream between Y pipe and muffler


Friend, your car has only one (1) catalytic converter. It may have one or two mufflers. Tenneco makes the Walker brand of mufflers and catalytic converters and have many for most cars. Check their online catalog to see it a system is available for your car. I would recommend you replace the one or two Oxygen sensors at the same time... poor gas mileage is often the result of failed Oxygen sensors. Most cars have two, some have only one. One may screw into the exhaust manifold (header pipe) and another after the catalytic converter. Good luck ;)

With any luck...
This years tax time repair could just be that leaky exhaust (Rusty muffler or plugged CATALYTIC CONVERTER)..

Annual repair is pretty good... (better than most)
but the TWO you don't want to put off

Brakes & Exhaust (ignoring could be fatal).

Just know your prices before going to the
local friendly EXHAUST SHOP.

Starts misfiring and dies after good start


pull your plugs and do a compression test and a leak down test. make sure the engine is cooled down before you take thew plugs out. first thing you may want to try is to check for vacuum leaks, if you can keep it running, spray carburetor cleaner at vacuum lines, throttle plate mountting and along the intake as best as you can. If at some time the engine pulls down then you found a vacuum leak. check for more after you fix it until your sure all is right. You masy have clogged EGR passages too.

My car seems to all of a sudden shake when I accelerate and then the muffler makes a weird noise and it dies. I try to restart but will not restar...then I leave it for like 15min and then it will start....


Coil or ignition module may be getting hot and failing but the Most common cause of an engine that stalls and will not start back, but starts after it sits awhile:

Clogged catalytic converter. It lets your exhaust gasses build up backpressure and it can no longer breath. The pressure releases over time, allowing your engine to start again, only to build up the backpressure again.

I have a 92 mercury sable. when I start the car it's like doesn't want to stay on. It dies after like two mins even if I give it gas. Even when I'm trying to give it gas it's like the car...


the catalytic converter is an exhaust component and while it is possible that its clogged its unlikely. If it is clogged your check engine light should come on.

1.) you more than likely will not be able to replace your catalytic converter yourself, more often than not they are welded in place before your muffler

2.) check fuel filter it is more likely to be the problem

The cat converter has started making a vibrating noise do i hsve to replace


A vibrating or rattling sound coming from around the area of your catalytic converter is much more likely to be a problem with the heat shield that wraps around the top of the converter to keep it from damaging the floor of your car. A noisy, rattling heat shield is annoying, but it can be ignored without damaging the car.

A catalytic converter that is failing is likely to make a "whooshing" sound like a muffler with a hole in it. Or, if your cat suddenly plugs up because the inside has come loose, your car will suddenly have no power and you'll have exhaust gas trying to escape from every gasket in the exhaust system. It's a very distinctive (and expensive) sound, compared to a loose heat shield.

Some people simply remove their noisy heat shields. Others pay a welder a few dollars to tack it back into place. It's a simple problem to diagnose, especially if you can put the car on a lift and get underneath it to wiggle parts until you identify the loose section(s).

Replace muffler, not the catalytic converter which started to rattle. Stop running, will crank but will not start. can it be the catalytic converter.


if the converter is rattlin then it needs to be replaced because the element inside is broken. if the jeep still does not run try removing the catalytic converter to see if the restriction is too much. should start if the converter is restricted. if it doesnt maybe its whatever caused the converter to go bad in the first place

NO run


sounds like you have water frozen in your exhaust system (muffler) or your catalytic converter i plugged due to an over rich fuel mixture overheating the catalytic converter.
