i recently brought a 2.2 vectra sri 51 plate (3weeks ago) and have noticed a strange lumpyness when idling however it only happens after around 10 secs of coming to a holt, notsure.gif it seems to fluctuate between 650'ish and 700'ish as i work in a garage ive checked for fault codes (nothing) replaced plugs, fuel filter, air filter, tried different fuels (bp,shell,texaco) ran 2 lots of fuel treatment through but still no change i do have a set of coil exstentions to fit wednesday, i also spoke to a mate at vauxhall who said it may be clogged up in the throttle body and mite need a good thrashing so after a week of heavy right foot driving and no change im stumped??? ive had a couple of mates sit in the car and feel it but they say its fine and im being over picky but i had a 2.0 sri before and it was so smooth u couldnt even tell it was running without looking at the clocks..
has any1 else suffered this problem or is it just me??
thanks in advance for any help or advice :thumbup:
