Hi folks, i have a 2001 vectra b 2.2 SRi, Only got Car 8 weeks, has drove like new untill earlier today. its been driving like a pig since, Started holding back and misfiring sounds like its running on 3 cylinders then drives ok for a while.
problem don't turn the engine management light on.
First 2.2 vauxhall i've owned so don't know much about them yet :confused:. Have a haynes manual, so i checked and cleaned the spark plugs, also checked connections and vacuum hoses for leaks etc. all seem ok.
Any info welcome folks!
