hi all got a 2.2 vectra b sri with a couple ove anoying faults.
have a slight miss on tickover seems fine when driving. changed the plugs and 1 was slightly blacker than the others so guessing thats the one thats missing. but what could be the problem and anyway ov working it out without going through all the parts 1 by 1.
next problem when i change gear the revs rise about 500-600rpm it so anoying and makes it sound like i carnt drive.
its always had these probs, work i did the other day, i cleaned the throttle body and butterfly, did the airbox mod, removed egr valve used cheater kit, changed plugs put k&n panel filter in.
car drives alot better but those 2 probs are still there
any ideas please people
