I have a 2008 bmw 535xi with 105k I recently replace all my injectors because I was having misfires and I change my sparkplugs and coil but the problem still there.i coded my injector with inpa I did everything right but still. In the morning when the car is cold turns on like nothing but once hot and I start driving it start the misfire but only happens on cylinder 1 and 6 and I even move the coil around and nothing works.. But I have a bad o2 sensor so what questions is can a bad o2 sensor

Codes p142e

Im not understanding why you replaced the injectors and coils. Where they bad? Did you do a test on the injectors? It seems you wasted money and time without correct diagnosis.

I would put my bet on the HPFP and Low pressure fuel sensor. Change those two out and your issue should be fixed.

I went to the bmw dealer so they can run a diagnostic to see what was wrong with the car and they end up telling me that I had a misfire on cylinder 2 and 5 and that I need to change my spark plug and coil to see if that fix the problem and if the problem keep happening then I need to replace my 2 and 5 so I end up just replace all of them at ones.. But my problem keep happening and when I use my obd tool it says CYLINDER CUTOFF BANK 1. So I don't if a hpfp problem or what?
