Just did a head gasket job on a 1997 E36 M3 with S52, shark injector tune and M50 manifold conversion. We got the car all buttoned up and back together, and it runs great, but it's throwing a few codes that it didn't have before and does have a very slightly (and I mean very slight) rough idle.
I have a feeling the VANOS is out of time, but before I go tearing the whole car apart again, I figured I would come here and confirm my suspicions...
I get the following codes out of my Snap-On Ethos:
VANOS - mechanical fault - 212
Misfire Cyl 5 - 242
Misfire Cyl 6 - 243
Misfire Cyl 2 - 239
Misfire Cyl 4 - 241
Misfire Cyl 1 - 238
Misfire Cyl 3 - 240
The only thing I have to add is we installed NGK BKR6EK plugs - copper. I've had various experiences with both BKR6EQP and the BKR6EK on OBD1 and OBD2 cars, so the copper plug was my first resort. I doubt that the copper plugs would have an issue like this, but it was worth mentioning.
Any suggestions are appreciated.
