Engine Performance problem
2004 BMW 330 6 cyl Two Wheel Drive Automatic 51000 miles
the car has a rough idle except when completely warmed up. 15 plus minutes of running. The things I have done. Fuel filter, oil change, air filter, compression test on #1 and #2 150+psi, cleaned MAF, checked for vacuum leaks around intake, MAF, hoses. The service engine soon will come on 2 out of 4 times. Initially it had a lean mis in cyc 1 code but not since the first time I checked the codes 4 weeks ago. I am still driving it every day with chevron gas plus fuel injection cleaner. PLEASE HELP! Ps I will be doing all the repairs.
have the same problem?
