I got these codes after replacing my valve cover on my BMW 528i 2012, N20 engine. Car is rough on start up, it shakes and makes a strange noises. RPM fluctuates up and down as well for about 5 seconds. Drove the car and it takes a minute to get to speed when accelerating/ jerks. drives fine at constant speeds but may shake if at a stop for too long/ RPM fluctuates and in park. Started car with MAF sensor disconnected it did not happen at all. What should i check for?? ugh
