Hi, PLEASE HELP!! I have a 2001 330i. About a month and a half ago the car was idling rough, running lean, misfiring, super down on power and appeared to be in limp mode. I found the issue to be a bunch of torn inlet pipes and a faulty MAF sensor. I replaced all of these, scanned with the scan...

Hey folks! I have recently done quite a bit of work on my engine and got it all put back together! Now, I've come across this idle problem that I can not diagnose and have tried to research it to no avail. My hope is that someone has come across this issue before or will be able to help me...

Hi everyone, i've been digging around trying to solve this issue for a while, but can't pin-point anything specific. I've got an 03 325Ci, manual. 143k miles. The problem is as follows; I'll start the car, pull away fine. I come to a road exit for example, fully stop, now when I go to pull out...

Is this an ok idle? Or should I look into something

Ever since I bought the car, there was been a rattle when it's idling. This only happens when the car is in "Drive," or "Park." The engine runs smooth, it has no problems accelerating, and it has always runs strong. I guess since it has never progressed, the idle hasn't really been an immediate...

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...

Hi, guys i have a wierd problem and need your help. My e46 with M54B22 and auto tranny vibrates on warm engine. When i disconnect MAF it stops vibrating. I've tried 2 working MAFs but no difference. And no IT'S NOT ENGINE MOUNtS. Also fuel trims are around negative 7-8. MAF shows 12-13 kg/h on...

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...
