    Default Revs surging up and then dropping back when giving to some welly!

    Hi Guys,

    Had the Vectra for a good few years and had a few issues which I've sorted sucessfully. One which has been elusive all along is that the Veccie goes into limp mode every now again on long climbs and when applying some welly!

    To add to it now, when I apply some welly to the accellerator,the cars revs shoot up (as you'd expect) and drop off almost straight away - and then slowly back up where you'd expect them to be. I suppose you could say that the responce of the car is not what it should be!

    Has anyone come across this sort of issue before? The car in question is a pre facelift 2.2dti. Any help on this would be much appreciated.

    Cheers, Chris

    Ours does just that I find it irritating tbh...

    As for the limp mode when accelerating uphill...I've done some research on this a while back when our car was doing it and apparently it's the turbo going tits Might be in good shape (no oil consumption), but something in it makes the car go into limp mode...

    Doubt it's alright though as it's started doing it about a year ago, when the new gearbox they had put in had 15k on it...oh well it only does it occasionally and I rarely drive that car anyway
