My Ride: 323I
323I's are a pain in the a*s when It comes to misfires, I replaced my maf, coils, fuel injectors, intake boot, ccv, fuel filter and had a smoke test done after everything, still didn't fix the problem. Do you know what was done at 100k maintenence? My misfires were finally corrected after replacing my precat o2 sensors. I only had misfire codes too nothing pointing at the o2's
