    Try this for smoother on and off throttle reaction

    Hope others fin this useful, not sure if it's been covered before.

    It relates to the snapping of the engine when one is accelerating in say second gear on wot and then you have to come off the accelerator to touch the brakes, and the engine doesn't like having the throttle effectively snapped shut.

    I looked at the little faded beige throttle damper with the little red boot, in my case I bought a new one and fitted it, but here's the thing, I adjusted it so that the throttle only just clicked off its's micro switch that you can hear as the throttle spring returns it to it's fully closed position.

    This means that the throttle body's butterfly can't / doesn't shut as violently as it used to and so therefore the car is much smoother to drive when stepping on and off the throttle.

    Maybe it is just my car, but the yellow seal paint was still on my original one and the two dampers compared side by side seemed pretty much the same feel when compressed and therefore it probably will not be necessary to buy a new one, but just adjust the existing one.

    It may have effectively gone out of adjustment with age, and needs to be readjusted tighter to perform it's original intended function.

    See what you think, it costs nothing to adjust.

    Hopefully it is as I describe on other cars, and not just on mine or my driving. It is probably more noticeable with either or both a worn std front snubber mount or worn gearbox mounts.

    Someone more adept than me might post a photo of the throttle damper to allow others to get a quicker / better appreciation of what I'm waffling on about?

    Thanks.

    Did you have any funny idling issues before changing / adjusting the throttle damper ?

      i have mine wound in pretty tight. what you find is over time the first bit of it gets soggy so the transiton time is less and the trottle is basically closed then bufffered.

      i dont think a couple of turns does any harm.

      as you know paul its about listening for the click on motronic as it settles back

        Paul,

        Pre and post "modification" idling was and is perfect.
