Bank 2 misfires and violent shaking | replaced everything | need help
2009 328i N51. I have consistent misfires on Bank 2 cylinders 4 5 6. The car shakes violently only under 1k rpm, but runs just fine over. Removing the eccentric shaft sensor seems to solve misfires and the car no longer vibrates at all.
02 sensor readings add up to 5v so I can rule out bad 02 in bank 2. The only thing I've found to be odd is a slight deviation in the Eccentric shaft actual vs target by about +- 5% under all conditions.
The only code that shows up is misfires. I have recently replaced the vacuum pump, valve cover, spark plugs and coils, MAF sensor, VVT solenoids, VVT sprockets, VVT check valves and checked ground wires for bank 2.
could it possibly be the whole Esentric shaft?
