#1: Lazy revving when warm and rattle on acceleration Author: adders, Location: NorthwestPosted: Wed Jan 19, 2011 1:52 pm ---- Hi,
I have a 2002, 2.0L 206cc. It has just had cam belt, water pump and tensioners changed. Prior to this the car was perfect but now the car revs really slowly from idle when stationary! Strangely the car still pulls like a train and doesn't misfire at all. It idles perfectly but as I say when you rev it is slow to react. Another fault which wasn't there before is a buzzing/stroke rattle when accelerating? The garage has had it back and checked: Emmisions - fine, lamda sensor- fine, fault codes on computer- none found. Cat removed and checked - fine.
Any ideas or suggestions please?
Thanks

the rattle noise could be pre detonation within the cylinder due to the timing being slightly out?
do the revs drop at the regular speed?

I made the garage take the belt off and re do it. They re did it and he assurred me that the timing was spot on. I suppose it would run awful if it was out but it doesn't, it runs ok.
There doesn't appear to be any pinking at all so im wondering if the noice is due to loose pipes in the manifold? If it is, that wouldn't cause the lazy revving I don't think..
Its a strange one!
