    Default 03 xp DI misfire

    :emoticonc I have a 03 xp di that always sounds like it's misfiring. If you try to hold the throttle at 3k rpm's the engine rpm's will very

    up and down by 600 or 700 rpms each way, that a 1400 or more swing. It also seems to be cold blooded some times

    starts fine but when you give it gas it stalls, restart it and give it gas and it stalls again over and over 6 or 7 times.

    The computer never show any codes?? Has any one with a DI seen anything strange.

    Do a compression check, make sure your RAVE valves are operating correctly.

    Has anyone been told to put a ground wire from the 947 eng block to the
    engine head to help with the grounding of the head???
