Managed to borrow a snap on diagnostic machine, it came back with p0301 cylinder 1 misfire detected. Reset faults and swapped cylinder 1 and 2 coil packs and the fault didn't log again but car is still lumpy.was there a recall on the coil packs for 2009 models ? I'm planning on just swapping over one coil pack or should I change all of them and spark plugs ? Anyone got the part numbers
