cold start issue

  1. General E46 Forum
    I got a 2002 325i with the m54 -150k Miles About a week ago I started experiencing trouble only when cold starting my car. When I go to start the car after sitting overnight it starts up and runs, but while it's turning over the RPMs bog down and the car slightly shutters but then starts. Over...

    Hey guys, I've owned an e46 coupe n42b20 engine bmw for the better part of a decade now, a few years ago i tried doing a burnout(like a f"in idiot) and because my drive shaft had a bad rubber bushing and flex disc cracked, the car shook itself stupid, and the major trepidation triggered a limp...

    Hey Guys, new poster here! Recently, I cleaned my IAC valve and throttle body and replaced a crumbling fuel pressure regulator hose connector; after starting up my car I found it had a rough cold start. I can often hear the IAC valve knocking very loudly while the revs bounce around for a...

    I've been fighting a rough idle issue on my 2000 328i for the last 4 months. The funny/sad thing is, I've owned the car for only 5 months. Back when I bought the car, it had a cold start idle fluctuation, so I immediately replaced the vanos seals. About a month later it began idling rough again...

    So I recently bought a 00' 320ci with 145k miles on it and it has this problem when it's cold it usually starts but it has a rough idle and has no power for the first few minutes. And sometimes if I give it some gas while it's running like this I can hear a loud pop... I've also noticed if I...

    Car is a 2004 325ci, made in Mar. 2004. NOTE: I called it the "GM5 tranny" because it's made by GM and the part # is 5L40-E. However I'm aware there is also something called "GM5" which is the "general module 5" that controls many functions of the car, and which is also a part found on the...

    I bought my e46 around a month ago and have been having absolute nightmares. It's a convertible 330ci 2001 and in the morning most mornings it has been misfiring and when I press the accelerator it's very limp and sometimes just dies. I generally hold my foot until it sits at 2000 revs until it...

    Just bought an 03 zhp sedan w/ 145k and I love the car except this one issue. I've had it about a week now and it drives flawlessly once it's warmed up, but every morning I experience the rough idle and a violent shaking. By the way it's about 80 degrees so it's not an ambient temperature issue...

    I had an issue today with starting my 2001 330ci. I went to start it, and it would turn over, but it would not start. After about 8 tries, and cranking it way past a reasonable amount of time, it finally turned over. I shut it off, and it immediately started again. I took it out, and made...

    After reading various post on how dirty the ICV could get, I decided to take a look at mine. While furiously working on removing the horribly positioned hose clamps on the throttle body intake boot, I noticed that the line that runs to to the ICV off of the main air intake was just hanging in...
