My BMW is rough idling on cold starts. Stumbling down the road, idle surges up and down really rough.
Got 2d2e codes and mixture codes for both banks
Mostly bank 2 is very lean.
Idle surges really bad at cold.
Did the fuel injector test. Replaced two of them.
I also changed the MAP sensors, new throttle body, new MAP sensor, new lpfp.
Hpfp not done.
Rest of the fuel injectors didn’t seem bad.
I replaced all 6 coils and spark plugs.
And done the valve cover itself along with new PCV vent hose.
I’m running around circles here with what’s going on.
I tried smoking the intake with no results. I’m fed up at this point.
