    Question Misfire Mayhem

    I HAVE A 2004 ASTRA TURBO , HAD THE FRONT WHEEL BEARING REPLACED THEN ENDED UP WITH A MISFIRE ON 2&3 CYLINDERS, HAD IT TESTED ON 4 COMPUTERS , DONT KNOW FAULT CODES , REPLACED COIL PACK AND PLUGS .CAR RUNS FINE WELL SAT ON MACHINE.
    WHEN REMOVED FROM COMPUTER TICKS OVER FINE 4 2MINS THEN FAULT RETURNS .JUST HAD TECH TEST DONE AT MAIN DEALER WHO SAY IT NEEDS NEW TURBO AND PLUGS. CONFUSED HOW A TURBO COULD MAKE IT MISFIRE ON TICK OVER OR HAVE I GOT IT WRONG
    PLEASE ANY ADVICE .SQUIFFY

    my car kept misfiring, but wasnt putting up any fault codes.

    turned out to be the plugs, coil pack and afm!

    sounds like your afm might be stuffed then. try disconecting the afm and see if it runs better or not

    I'd check the plugs too, get them out and check the state of them. Missfire on two cylinders hints at something else though.
