Like many other people, I had the same problem with the car dieing. It never happened frequently. No problems restarting afterwards.
My symptoms included rough idle, bouncing RPM, RPM gauge dropping to 0, and stuttering.
On a hot day (around 105F) was driving and the car suddenly dies. And would not restart. Checked everything and couldn't find anything wrong.
I had it towed and it sat at a shop for almost 2 days. I called and they said they couldn't figure it out and the diagnostics were good, didn't reveal anything wrong.
After doing some research on the net I called the mechanic back and told him some of the solutions other people have had with my same problem.
I told him about the Crankshaft Position Sensor and he called me back and said that was it. They wanted $150.00 for the part and another $50.00 for repair.
I called around and NAPA had the part for $45.00. I went to pick up the car and the mechanic wouldn't even tell me where the part was located cause I was going to put it in myself. So I sat in the parking lot and finally found it. It's on the backside of the transmission. I plugged it in, car fired right up. Flipped off the mechanic and peeled out of the lot.
Hopefully that will help some of you.
My car currently idles horribly and I'm having transmission issues _again_. Fuel filter has been replaced with a high quality one. Ran fine a few days now it runs even worse. New plugs, wires, distributor cap, and belts. Still same problems.
Took it to a transmission shop, cause I was more concerned about that than the idling. But the mechanic said the car runs so poor he can't even get the transmission to perform. So, I'm really wondering if the car is even worth it anymore. It has been parked for almost 2 months now.
This is the second Chrysler vehicle I have owned, both had similar problems. My old one blew a rod. I really love the car, but will not buy another Chrysler again.
