Hi
Iv got a popping/spluttering noise coming from the tip of the cars exhaust this more present when engine is first started from cold. Engine management light never comes on but my code reader keeps bringing up multiple/random misfire and misfire detected in cylinder 1, none of these codes are listed as not present but have cleared them lots of times and within a few days they reappear. Tried doing a full service including new coil pack and plugs. Old plugs had been in about 6 month and a few of them appeared to be (slightly)dark sooty colour and one of them had a chipped centre porcelain?
help appreciated
