Misfires on 1-4
Hi all, got a 211 e63 with m156 engine. I've got a code on startup p0333 which is knock sensor circuit high input bank 2. Last night I was driving on the highway and my CEL started flashing and the car was missing like crazy. Misfires on cylinders 1-4. Is the knock sensor the culprit or could it be something else? My car is only running on 4 cylinders at the moment

oxygen sensors since its only one 1 bank.....and if that isn't the issue, then ignition coils. the M156 is very sensitive to oxygen sensors that are outside of range.
