A4 130
I've changed the plugs, ht leads and coil pack. Its been serviced yet still suffers a bad misfire!
Recently its been run on shite Co-op petrol as Shell is closed, I've filled it with v power and added some injector cleaner to see if it'll solve it but so far hasn't (only filled up half an hour ago)
It doesnt do it all the time, sometimes it wont do it at all yet others as soon as its started it misfires, even on tick over. It occurs throughout the rev range but disappears higher up over 5k etc.
Is there anything else to check bar the injectors?
