I need help. Again.
My car has a problem that only happens when it's warmed up, or at full operating temperature. When the problem occurs, I cannot give the car more than 1/4 throttle. If I do, the engine immediately cuts out. Nada. Nothing. If I back off quickly, the engine sometimes resumes running. Otherwise, it dies. However, I still have battery power going to the radio, lights, etc...
I *thought* this problem was due to a bad ignition module or coil. I replaced both recently, ensured proper grounding, and the problem still occurs. Like I said earlier, the problem is NOT consistent. It seems to occur only when warm, and always at the same position on the throttle.
The ECM is not showing any codes. I "tap tested" my LT1 MAF and it seems OK. I'm thinking that it could possibly be my TPS, ECM, or maybe a strange grounding problem.
Could anyone give me some more possibilities on what the problem might be? Thanks!
