2004 BMW 325 6 cyl Automatic 80,000 miles
Have received these codes for exhaust system, as system says it is running lean so cleaned the MAF, ran fuel injector cleaner through the gas and replaced the air filter. Had the system reset, and codes went off for ~ 3,000 miles but now have come back on. Was planning on replacing the fuel filter in case there was slight blockage, but wondered what else would be feasible.
