    Default revs drop too 500 then rise back to 800ish

    When i put the clutch in when stopping it lights etc the revs drop right down to 500ish the rise again to tick over speed (800ish)

    im very new to my vectra so unsure if this is anything to worry about or not.

    Its a 2003 sri 2.2

    I wouldnt really worry about it unless it starts to affect your driving. Unbolt your tb and give it a good clean, the 2.2 has no ICV so if the butterfly gets dirty then the revs can drop a little. HTH

    If you take it off there will be a puddle of oil in the manifold, try and get that out too. If you really want to go for it then you can take the egr off and give that a going over as well but tbh it doesnt get that bad on a 2.2 petrol.
