    Hey all! Been a long time lurker, first time poster. Just for background, I drive a 2005 330xi, and I bought it used about 7 months ago - currently has 260k km. So I have a peculiar issue, and maybe some OBD2 expert on fuel trims can help me out. A few months back in the winter I had a lean...

    I've not been on this forum much recently, but I picked up a neglected 2001 330Ci with a 5 speed swap and some other goodies (M3 rear end, Konis, headers, etc.) and it's having issues... Anyway, I've been reading a lot on here and it has helped some, but I getting some very bad performance from...

    Hi gentlemen, I did a starter replacement job a while back. Have an xi AWD so it was easier for me to get to it from the engine by removing the intake manifold than to go from the bottom due to the diff and other extras down there. I took off the manifold, replaced the starter, while I'm there...

    Hey e46 fanatic, I posted the same problem a while back but due to moves and life changes never actual got to posting any updates: back story, while back my '00 BMW 323ci started running lean. Rough startups, intake backfire, boggy acceleration, codes P1188 and P1189 (with a few...

    My car recently got engine code P2195 with the description O2 Sensor Signal Stuck Lean, I also got two pending codes P2197 and P2195. Bellow I have attached Freeze Frame data and a 5 minute warm idle. What I do see is both bank 1 and bank 2 fuel trims are ~27% which calls for a really lean...

    I have an intermittent check engine light with P0174 (Bank 2 system too lean) and P0172 (Bank 1 system too rich). I just replaced the cylinder head, and a lot of the vacuum lines were old so I replaced everything that I saw. The CCV is new. All gaskets were replaced. There is one line, however...

    I apologize - I know there's too many of these, but I didn't want to hijack another poster's thread, and the resolution to my issue may take a different direction. I've read every thread I could find here and elsewhere, and have eliminated many of the common diagnoses for my Lean Code...

    Hey everyone, I'm new here and in desperate need of help with my 2001 330ci 5 speed. Recently it's been throwing lean codes(both banks), but bank 1 O2 sensor is reading .10v constant while bank 2 is fluctuating like it should. It has misfire on startup on cylinders 1,2,3(bank1). And now is...
  12. DIY: Do It Yourself
    The purpose of this post is to explain my diagnosis of the misfire problem my car developed. So my 2003 330xi threw a misfire code, and began to idle funny. I drove it home, and began to try to diagnose the problem. My code reader pulled a p1347 code. Misfire with fuel cutoff. I cleared the...

    OK folks hope you can help me with my problem on my 14 year old 330ci with 122k miles on the clock. I've been getting the check engine light with P0171 and P0174 codes, over the last 20-30k miles, with it gradually coming on more frequently. Initially the light only came on in winter and on a...

    Hi, the other day took my car to the car wash, when going into the tunel the car stalled and shut down - i tried several times to turn it on again but when it turned on it began misfiring with rev's going up and down between 500 and 1000 repeatedly, then the asc (traction control) light popped...

    I need help from you e46 experts, especially those with INPA experience. Unfortunately ideas from the e90 forums are not flowing in as I had hoped. Whenever I search for INPA and lean it directs me to threads here. The Story: Cliffs Notes --> Car runs lean and I don't know why and can't...

    My 2001 325xi just put on its 190 thousandth mile the other day, and it's still going- but less than strong lately. I know for a fact that the bank 2 sensor 2 oxygen sensor is out, that trouble code has been present for a little while. I'm planning to replace it next Saturday. I don't think it...

    Hello everyone, Just got my first "Service Engine Soon" light. :banghead: Happened yesterday just after starting the car after work around 7 PM. The car had been sitting since 1 PM and it was very cold (10 F). I borrowed a code reader from Advance Autoparts (Accutron I think) and got the...
