idle

Hello everyone! After getting my jumped timing chain fixed I now have some problems on my car. The idle is unstable, and i can feel vibrations in my cabin. Also when I am taking off from a stop, or press the accelerator >50% i can feel it stuttering and almost choking so I have to take off...

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...

Hey guys. So I have a manual 2006 M3 (~110k miles, VANOS and timing system replaced 1k ago) and it was our first cold day here in North Carolina with temperatures being around 30-35 degrees. I started up my car and waited about 10 minutes for it to warm up (coolant temp ~65c). I then drove 15...

Hello everyone, First off I would like to thank the huge community of E46 BMW enthusiasts. without the help of you guys, I couldn't have reach the level of knowledge and experience I have today. almost every common issue is reported here with fixes and steps. I was able to revive my 2001 330ci...

I have a 2004 330i with 110,000 miles on it. In the year I've owned it, I've replaced nearly all gaskets, hose, seals, bolts, and nuts. All of this was to fix an oil weep at the rear main seal and hunting idle. Everything I do has no impact on the hunting idle. I start it up, it goes to 1K...

I have searched and read as many threads as possible and haven't seen anything that quite details what my car is doing, so I hope someone on here may be able to pinpoint it or at least point me in the right direction. On my 2001 325 xi wagon, I have idle issues no matter what temperature it is...

Hi there! I’ve recently purchased my 2008 335D and and it’s been running sweet as a nut up until this morning. The cars sitting at about 88k on the clock and as I got to work and sat in the car park I noticed that it was idling rough. It normally sits about 800rpm on idle but sitting this...

Hi all, I just ran an OBDFusion log. Cold start followed by ± 10 min driving home, top speed 70 mph. Would you all mind having a look? Would like to know if all looks fine. Cold start idle is a bit rough at the moment, otherwise the car seems fine. You can ignore the fault code in the...

Ok, I'm at a complete loss here. '01 325i m/t. Idle is bouncing coming to a stop (shift to N or clutch in). Drops down to about 500 or slightly under bounces back up to 900-1k and just continuously bounces the whole time unless I feather the gas a little and settle it at 700 myself. Sometimes it...

Okay, so I have a 2001 325i and it recently started intermittently shuddering while driving, mostly at highway speeds but sometimes while driving in town. This only happens when the car is not under a large load or accelerating, just when cruising at a constant throttle. The car also...

So, a while back I noticed that I was getting a certain whine/whistle from my m3's engine bay while driving. The whistle only appears when using light throttle at speed, maintaining speed, or when going downhill. The whistle generally starts around 2500rpm and gets drowned out by the engine...

Hi everyone, I have done my research in terms of my problem but nonetheless found inconsistencies so essentially I want to ask what to do next? The Story: I have a project-ish e46 sitting in the garage that I am turning into my summer daily. The car has o2 sims (which I'm still trying to...

Hey everyone, thanks for stopping by. Hopefully you can help me. My car, as the title states, sounds like a diesel. Also I have loss of power at the low end and a hunting idle with lots of vibration. The engine has a loud tick as well. Yes I rebuilt the Vanos and the problem started withing two...

Hi guys! I've had my 2000 E46 328ci for just over 2 years now with around 115,000 miles on it. For the majority of my ownership, it's had the roughest idle, along with a big loss in bottom end torque. Along with that comes the crap MPG and intermittent P0170/P0173 code, which only happens on...

Hi! Thanks for wanting to help!! 2003 bmw 325i. (M54 - Automatic) Car ran really rough before I started work on it. Shaked/ran very rough....Had to put it in neutral at stop lights to keep the rpms up so it wouldn't stall. CODES before working on the vehicle: P0171 (system too lean Bank 1)...

I've run into a new problem recently with my M3. When at idle my RPM will drop by about 400rpm whenever I turn the steering wheel (with AC off). It also does this when I disengage the clutch to come to a stop. It gets low enough to cause vibrations in the cabin. Not enough to stall the motor but...

I'm trying to figure out what's up with my car. I had an idle issues many months ago I fixed doing the fuel pump/filter. Now I'm having a new issue with the idle dropping to 550 thru 500 ish with the heat on. Normal cold a/c isn't an issue. It's just when I turn the control to the red dots near...

Hello, I am looking for a quick diagnostic for the 330ci I just bought. The story is simple, I went to test drive a 330ci 2001 with 124k miles on it. When I tested it the car ran smooth and right. The car was stored for 9 months and got serviced when it came out. Only now, two days after the...
