It is only now and then. Not every time. When starting from cold it starts rough. Like its running on 5 cyl. After a little while it throws the CEL. Misfire Cyl3 (P0303 Cylinder 3 misfire) or last time it happened Misfire Cyl2. (P0302 Cylinder 2 misfire). After the rough start, which lasts like 3 - 5 secs, it runs like champ. Spark plugs are new. AOS new. What are the likely faults? Coil packs?
