I have a 1.6 Astra Mk5 Twinport, 54 plate, registered Jan 2005. Engine code Z16 XEP. The engine management light (might actually be an emmissions light) has been on for a while and it has had misfire problems. The car actually runs well on the open roads and the misfire isn't really noticeable. But when idling and in the town its slightly noticeable, but I can live with it. So I've done the old ignore it and hope it goes away thing! But now the MOT is due and I suspect it will fail on...
