Hi guys ,
hope you can help me car got vibration through rev range, had chains replaced still doing it . As new to vectras need some advice , when you come to stop the car and you put the clutch in the rev counter goes down to 500 rpm and when you fully stop slowly goes to 750 rpm. is this normal ? if not can anyone point me inthe rright direction as to what it could be please.
What would be the efects on the car if a coil pack is playing up?
I think it seems like an electrical fault but not sure how to check it out , car seems like its not very fast at pick up, for a 2.2 sri.

Please help.
