Service Engine Soon Light
Howdy All,
I have an 04 330ci with a Service Engine Soon light on at 100k…. I have replaced the fuel pump/filter and all 4 O2 sensors….. The computer keeps giving me an error saying the engine is running to lean… Anyone have any other ideas besides sell/trade it in? LOL
thx

You have a restriction in the air intake, or a faulty sensor on the front side of the engine (ECT, Ambient, IAT, etc.) or a vacuum/air leak. It's most likely actually causing a lean condition and the old stuff as well as the new stuff was/is reading right.
