    Post Whining and idle problem

    Hi just a quick one when I start my car when cold there is a slight whining noise the accelerator pedal is also slightly harder than normal and if you rev the engine slightly when the revs drop back down they go far to low and sometimes makes the car stall. When starting to warm up the whining goes and the pedal goes back to normal, any idea guys?

    Cheers in advance

    crystal ball aint working tonight, so youll have to give us some car details

    engine, year, etc


    sounds like some sort of cold start feature and perfectly normal

    depending on engine and year it may be a good ideal to remove and clean the TB, EGR & ICV where fitted.

    The whining noise on startup is probably the aux belt tensioner - my advice would be to remove the aux belt to see if the noise goes when starting up without the belt fitted - obv just do this to fault find as the alt will not charge when belt removed

    if noise goes, then remove the tensioner and give it a good clean, wd40 and grease before refitting. Might want to slip on a new aux belt whilst ur at it
