I have not checked the Ecm of the PROM and that very well might be it. I was just wondering though if your car had the same problem as i explained or the same problem on the message board you found. My car died going about 20 miles per hour and would not restart. It would want to start and it would run for about a second or two and then die. Eventually i got it to start, but i think it was because i forced it. When it does run if u tap the accelerator it will die. It will not move, and the engine only runs for a short amount of time at an unstable idle and then dies. Is this the same problem you had?
