[QUOTE=Sam Granger;3161548]I'm not sure what's wrong with my GTV, I replaced the battery the other day and maybe thats what caused my problem but I doubt it (I just hope it's nothing serious *touchwood*). When driving, my car jerks now and then, usually just after changing gear.
Mate i've just got rid of this prob, took me ages, for me it was the clutch going, the light thats coming on is just a engine managment light, doesn't really have much to do with ur spark plugs etc.. best thing is to take it for a dianostic, or if ur clutch has been heavy for a while then i would suggest a change. mine would run the seem to lose power the light would come on then after abit of throttle would go away but jolt quite voilently when it caught. also started to die at junctions and the rev's would move up and down and then battery light would come on and the car would stall. as i said thou mine was clutch
