    :lmfao: My car has suddenly decided to start hessitating under acceleration.

    If you drive the car gently you do not notice at all but if you put your foot down the boost comes in and the car feels almost like it is missing and holding back. Does not do it all the time, sometimes it seems to clear and go.

    I have put another maf in at weekend ( not a new one second hand ) and still doing it. Also new plugs.

    VAG COM does not register any faults at all so I am a bit lost.

    Anybody got any ideas

    maybe dodgy coil pack?

    if not may be a fueling problem, dirty injector, fuel pressure low.

    Mine the same, used tescos and morrisons cheap stuff and car didnt go well at all, back on the V-Power (and sometimes normal shell unleaded) and all's fine and dandy and I get an extra 4mpg outta the V-power aswell as better throttle response and performance.
