From the FJOF thread, he had said to start a new thread when we do this so, I'm just following that. Prior to any work I did with the car, I was throwing 8 different codes, the...

    So I have the P0171 and P0174 codes signifying a vacuum leak and there's a hissing noise I can hear coming from the front left tire when the car is running. I was wondering if these two things are related

    Alright, I've put in hours of research on different causes of the Lean codes (P0171/P0174) and the Engine not running 100%. I've also done troubleshooting for most of it, and now I hope to present all the clues that I've found to someone who has spent a lot of time with E46s and who might be...

    Hello everyone I just joined today and Im a new proud e46 owner. I love the car except I'm being driven up a wall by this engine light. I get the two codes P0171 and P0174.

    Okay, I know hardly anything about BMWs and DIY car repairs in general, but I'm trying to learn how to do some stuff myself because I can't afford to keep taking my car into the shop to have work done. I just had 60k service / Inspection II done on my 04 325i about a month ago at an independent...
