Occasionally I have serious problems with my car falling flat on its face. It usually happens in a light throttle situation taking off from a stop sign. It did this with the old engine and the new one. The car will barely go, I'm talking like i got it up to maybe 10 mph in half a block. I pulled over, reset the EEC and it drove fine. I ran this code once upon a time and i didnt take note of the code number, all I can remember is that it gives me a MIL due to a high or open in the CMP circuit. It only sets the code when the car decides to do the whole "let me just fall on my own face" thing. It has probably done this 3-4 times in the past 3 months. I'm just curious because I think it might possibly have something to do with my problems of my car not detonating with the octane plug in and regular gas. Thanks!
