30ED & 30EF Codes - FBO N54
Hi all,
I have a FBO n54, and car is running really rough now with misfires. Car has new coils but not plugs, running index 8 & 9 injectors. Where should I start? |

It doesn't idle or cruise normal, heaps of misfires on idle and cruise, a lot when accelerating. It started off as just misfiring on cold starts for about 30 seconds or so, and then started doing it when idling. |

+1. Especially if it started with cold starts.
Pull plugs, bet you 1 & 3 and/or surrounding plugs are blacked out.
