    Well, the gearbox noise disappeared so no problem was found there. What a relief. Only now, to find out that our car has 2 fault codes coming up :


    Idle speed
    Stepper motor

    So now i need a brand new stepper motor, anyone ever heard of this, apparantly its going to cost me 280 quid + vat from a dealer. Why me, oh why oh why, im having nothing but problems /ubbthreads/images/graemlins/cry.gif /ubbthreads/images/graemlins/cry.gif /ubbthreads/images/graemlins/cry.gif /ubbthreads/images/graemlins/cry.gif /ubbthreads/images/graemlins/cry.gif

    On the plus side, its no longer overfuelling. Got an fse power boost valve instead of the adjustable regulator and it just wants to pull and keep pulling. So much power.

    The stepper motor was always playing up with my old car. Do you a bit of lag wen you press the throttle from idle or do the revs die then pick up? Find the stepper motor (near the inlet, got a breather pipe going to it usually) and spray some WD40 into the bugger, it usually just gets stuck and just need cleaning. Hope this helps.
