    Need Help w/ Intermittent Engine Problem

    Thought I'd add this too: Could it be a TPS or an O2 sensor? Maybe the ECM? I keep getting the same faults: cylinder misfire (various cylinders), CPS sensor errors, etc. Also, I wiggled the wire harness when it stalls to see if there is a bad ground but no amount of wiggling took care...
