    still cutting out

    Right, where to start ? Engine has been cutting out violently at anything up to 3000RPM.
    Will restart straight away.

    I have now changed the MAF and G28, this has improved the situation as it now happens only at or just above idle.

    I am also convinced, after doing an output test that the ISV is good and when you see the revs drop you can not catch it no matter how fast you stab throttle.

    Ignition switch also appears to good.

    Only fault code is "G28 implausible signal.

    So where now ?

    Going to take the starter off to check the ring gear and G4 peg.

    Can the clearance for G28 be adjusted ?

    What is the pin number/location of the G28 wires at ECU ?

    Is there anything I have over looked ?

    PLEASE HELP ME

    Did you test it with the engine running?

            Check your grounds to the intake manifold. One sounds loose.
