    04 virage I wont rev past idle?

    ok..ill try to sum it up fast.... ive got 2 04 virage I direct injection 800s..the 1 i just put a new motor into and runs great... the second was butchered by previous owner.. so i pulled motor and went thru everything.
    fix what was needed and re-installed.. went to start and started vary hard but would run for a few seconds and bog out.. then its started to backfire like a cannon!! so i got the good ecu from other ski and installed.. now it idles perfectly but wont rev past idle? before i switched the ecu i replaced the tps and sensor in intake housing from other ski also..im gonna try puttin the orginal sensor back in to see if that helps.. i check fuel lines for leaks and all the obvious!
    so if anybody has any knowledge they can throw my way, id reallllllllllly appreciate it!!!!!
    thanx for your time..

    Make sure the TPS is actually good and the connections to the TPS are clean contacts and undamaged wires.

    Anything else you might want to share with us?

    Check Engine light could be caused by several different things.

    Check ALL the sensors;
    CPS
    Air intake temp sensor
    Exhaust temp sensor

    Correct ohms, plugged into the correct wire connector, etc.

    Note that the exhaust sensor uses the exact same connector as the fuel injectors. Do NOT get these mixed up.

    If still not diagnosed, use a simple LED tool to read the EMM trouble codes. Details via my signature links.

    For anyone else who happens to read this later;

    If you are changing the TPS to diagnose a problem, the replacement TPS must be a new or known good part. If you do not know for sure that the replacement TPS is good, it can make you chase your tail with false symptoms and incorrect diagnostics.
