I have a 2001 Dodge Intrepid with the 2.7L V6. I have4 error codes. P1391, P0351, P0353, and P0356. Car runs fine for about 10 miles then begins to miss serverly, causing siginificant loss of power until it dies. I replaced both the cam and crank sensors, I have also replaced all six coils and spark plugs. Symptoms seem to be getting worse and i can clear the codes. What am I missing?
You most likely need a new pcm. If you let it idle and hold a hair drier near it and it dies faster than usually it is the pcm.
