Rough running Non responsive throttle w misfires @ 4, 5, 6

DieseLife_335d · 04-14-2020, 10:06 AM

I have a 2009 328i that is running rough and is throwing codes for cylinders 4, 5, & 6. It was also throwing code for bank 2 sensor 1 but I installed a new bosch oem sensor and that code went away. I have changed out all of the plugs which were in really bad shape btw as well as all of the coils. I have even rotated the coils since to eliminate that any of the new coils may have been bad as well. I also have a plug test light and all 6 are firing properly. So I moved on to the injectors and rotated the rear with the front and still same issue. I have also checked the fuel pressure which is around 68psi even under throttle. I checked #6 compression and was up around 190psi I am using Carly for BMW so I can read clear and data log but thats about it. Any guidance or help on this would be helpful.
