    Wiring

    Check the wiring around the front of the engine the two
    Pclips can rub through the insulation,
    Rub points for wiring around AC pump.

    This wiring is for the AC AAP MAF engine temp
    and wastegate modulator.

    So a short to earth or live can effect the ECM
    If modulator earths it will open.

    This is how I realised my MAF was dead. That and slightly unpredictable on the auto lock up as well.
