Have you run the car really hot?

We need more info and you've got alot of troubleshooting to do.

sorry for the delay. heres some info on the car, it has 131,000 miles. It has a brand new radiator due to a radiator leak causing my car to overheat. 2000 miles ago the car would not start and would stall. I replaced the optispark, plugs, plugwires, trans filter, and fuel filter at that time.

How did you come to the conclusion it was the PCM?
