1.2 misfire

[dooooney]

hi long time no see ppl i havent had a vauxhall for nearly a year now after selling my nova and going to a mini.ive had my fun with the mini and i got a corsa. its a lil 1.2i single point injection with dizzy. right ive had it 3 days payed 500 for it and its developed a misfire its fireing on all cylinders and ive changed the spark plugs but it still wont run properly it has a miss when idling. so me tings it may be a cracked valve ****ed head or headgasket. but hey what do i know so does anyone have a clue?

Are the spark plugs gapped correctly mate? Try replacing the dizzy cap and rotor arm and giving everything else a damn good clean. My Mums 1.4i LS had the same problem I'll ask her and Dad how they got it sorted when I see them next.
