    Eratic engine revs

    Well its a strange problem, when I drive to work in the mornings and get stuck in traffic the engine revs itself, up to 1.5 k and then to 1k and does this over and over. Any ideas what this could be?

    Also the engine revs itself under heavy braking if that is anything to do with it?

    Any help much appreciated.

    Yep thats the old throttle body problem by the sound of it. When you stop at idle its as if you keep touching the throttle a touch every 1/2 second. If its these symptoms I'd suggest cleaning the throttle body. There is a how to on here somewhere.

    Well that's a relief, thought it might be something a little more serious. Will give it a clean ASAP.

    And yes it is excactly how you said it is, as if you keep touching the throttle on and off.
