Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer. Does it eventually start to run better after it gets warmed up or not?
Ok, possible fuel pressure problem (fuel pump ) or if the catalytic converter came apart inside, then it may have plugged up the muffler. Get the fuel pressure checked next. It should be about 50 psi when running. If it is low, then have the fuel pump replaced. Fuel starvation can cause this.
Well not necessarily would you hear any schrapnel sounds, it would be gradual. By the way, I have never seen a TPS cause this type of a driveabilty issue. Double check that exhaust and fuel pressure.
On a fuel injected engine like yours, no. A vacuum leak would cause a high idle and eventually set a code and turn on the check engine light, however a bad EGR valve (stuck open). could cause an issue like yours, but would also cause a very rough idle, just FYI.
Yes I had just thought of that when I was typing. The EGR could be the problem.
You are welcome! It was a pleasure to help you!

Hmmmm, are any trouble codes being set?
I see, Well if it is only misfire codes, then maybe that ignition coil inside of the distributor is failing when it gets warmed up and causing a weak spark.. If you clear the codes do they come right back? Is it a certain cylinder tat is misfiring?
Yes that is correct. The coil is not serviceable separately, the distributor will need be replaced. And if you can, clear the codes then drive it until it acts up and then read the codes.
Let me know,
Yes you can do it that way. Remove the negative cable for 2 minutes and then reconnect it to clear the codes.
