E39 M5 and E52 Z8 Discussion
Hi, My M5 just started having issues out of the blue. It was driving fine, I let it sit for an hour then when I fired it up it's misfiring. I've got a bunch of codes.
The codes that were pulled:
P0303 Cylinder 3 misfire
P0304 Cylinder 4 misfire
P0300 Random misfire detected
P1354 Misfire...
