    Hello,

    A video says a thousand words?
    Does anyone know what's happening here:

    http://au.youtube.com/watch?v=U3GtehYadX8

    Try to accelerate but it seems to hesistate. Changed the fuel pump, map sensor and ecu. Before this problem the car was hunting, but couldn't find any vaccuum leaks.

    Any help will be appreciated.
    Cheers.

    P.S Do I need a better video?

    I am guessing either very weak spark, from poor ignition components (coil, leads, plugs etc.)

    or ignition timing adjusted wrong

    or not enough fuel due to low fuel pressure (pressure regulator), or poor injectors.

    I don't really know.

    Hey mate

    Have you done a diagnostic check with bridging ECU pin connector?

    Try that first if nothing turns up thru codes etc then look for vacuum leaks
    & check all your electrical plugs by removing the clips and checking for dirty pins
    etc.

    Possibly TPS?

    My car used to hunt because the TPS was adjusted wrong and seeing that it hesitates when you're trying to accelerate/rev... it could be a problem relating to that?

    sounds sorta like the timing is really outta wak

    TPS adjustment, coolant temp sensor and timing are the things id be looking at
