  • Slight hesitation

    Hello all,
    After some clues. I have a slight hesitation in my 3B at low and constent revs, when she idles she some times drops to 5-600 rpm until you put your foot on the accelerator then she settles out and runs fine, when you stamp on the go peddle she takes off like a ballistic missle, It is not a misfire and only happens on slow acceleration and constent throttle, WOT she is abserlutly fine, recently fitted all new boost hoses, plugs, leads dizzy, rotor arm and WGFV, any ideas would be greatly appriciated.
    All Hail the mighty Quattro

        Definitely worth trying washing out the ISV with WD40, sorted mine when it had the same symptoms, could also be the lamda on the way out though.
