    Does the car come right & idle normaly, drive normaly after the flick of throttle or always missfire, run rough?

    Idea #1 Air Flow Meter.

    Idea#2 Depending if your car runs fine or not after you flick the throttle.
    Check Coils. You can loosen them but leave them connected, put a spark plug in one coil at a time, get a mate to crank the engine & check for spark. Obviously do this one coil at a time untill you either find a faulty coil or not.

    (FYI: If it was a Crank Sensor your car wouldn't start full stop.)

    If you get that far with no luck, let us know....

    Cheers
