It wont stay running because the vehicle computer depends on the O2 sensors contained in the exhaust system to tell it whether to add or subtract fuel. Get the system replaced at a trusted muffler shop and save yourself some money as apposed to taking it to the dealer and you can use Bosch O2 sensors to help in cost also. Let me know what else I can do.

Why is my exhaust running like this?


could be a failing cat converter and the code would be refering to a roblem heated oxygen sensor (HO2S) in an exhaust manifold before the cat converter
have an exhaust shop check the cat converter as they do break up internally , rattlr around and in some instances can block the exhaust system

What would cause truck to shake very hard or rough when starting?


I really need to know the mileage.....?..also the question isn't very clear ...Is the whole truck shaking roughly or is the engine shaking roughly or is it both the engine and truck shaking..?..Since I am not sure I will answer what I can....Ok......If the truck is shaking while sitting still at idle the engine/trans mounts could be worn and or loose mounting hardware...If the engine is running roughly at idle causing all to shake that bad it could be a number of things causing it as usual...Quite often a faulty plug wire/and or bad plug will make it have a misfire because it will be running on only 5 cylinders..If that's the case it could be more than one bad...A vacuum leak will cause it to perform in the same manner...however all cylinders will be firing..Normally a vacuum leak is easy to pinpoint..however it could be a faulty IAC valve..(IDLE AIR CONTROL)..The idle air control is designed to hold a high idle at start up then slowly bring idle down to proper Rpm.....A faulty TPS (THROTTLE POSITION SENSOR) will also cause a rough running problem..And let's not forget the O2 sensor..(OXYGEN SENSOR)..The O2 sensor controls air/fuel mixture...and yes an exhaust manifold gasket will make it run rough but not too bad...It has a rough running sound more so than causing it to horribly shake..It will shake but not to bad..
it is located at the exhaust side of engine..The exhaust manifold is mounted to the engine exhaust port..the exhaust pipe is mounted to the exhaust manifold and the muffler/cat converter is mounted to the exhaust pipe...You can check the plug wires quickly..With engine running carefully remove plug wires 1 at a time..If the sound of engine gets worse the wire you removed is good..after verifying it is good or bad plug wire back on then pull the next wire..and so on..If you pull a wire off and there is no change in engine operation that is the bad wire..If that is the case change all plugs and wires...One at a time..(It is a good idea to make sure all wires come off easily before starting engine..old wires will come apart easily..grasp wire tightly at boot and twist left to right while pulling..)as far as the other components I spoke as well as many others,the best,easy way is to have it hooked to a scanner and they can check/test all components for proper operation...Now..If it runs good but is shaking the engine/trans mounts are worn as I stated earlier..any loose engine component will cause an engine shake also but you should notice it at a glance...engine mount bolts/nuts being loose can be tightened without changing mounts if caught in time..Trans could be coming loose.also worn clutch will cause vibration...Send more info and I can guide you to remove and replace any faulty components you may find to save you money.........Brooks/Metalpoet.....

The catalytic converter probably is failing. If you can pass inspection without it, you can save a lot of money by having it bypassed.

Loss power wont start maybe exhaust or catltic ?


I had a chevrolet cavalier once that had a clogged exhaust. i was driving and the catalytic converter fell apart, and clogged the exhaust system. I completely lost power, and barely got home. Try getting your arm under the car, and hit the catalytic converter with your had, or a mallet. If it has fallen apart and failed, you should hear a clattering sound. Try inspecting the whole exhaust system, looking for bends in the exhaust pipes. When my catalytic converter failed, i also heard a hissing sound when it was running, and the engine was slightly overheating because of the restriction in the exhaust.
!!GOOD LUCK!!

1999 TJ Wrangler/Sah runs rough after warm


we have the same problem on our 2004 dakota. The mechanic says that it could be the exhaust vacuum that needs to be replaced. Also, they also mentioned that sometimes when the catalytic converter is plugged it acts that way also.

Let me know if this helps.

Running rough, like not firing


Your "catalytic converter" is becoming clogged. The exhaust is not properly escaping, and the problem will get worse. A new catalytic converter will cure the issue.
