    check the ICM harness connector. I have had one where one of the wires were pushed back not making contact properly.

    Coolone and rickisrad I will check both places for any shorts or loose wires.

    fst I don't have the egg smell and I do not believe the exhaust manifolds are clogged.

    waupachino I had the injectors off the car and tested the flow when I did the intakes so I know they are not clogged.
