    Rough/low idle on warm engine - PLEASE help 1996 318i M44 - No codes I replaced lots of vacuum hoses (after smoke test), valve cover gasket, spark plugs, cleaned then replaced icv, cleaned battery terminals, replaced ccv, motor mounts, precat o2 sensor, and got a “new” used maf. The car...
  2. E90/E91/E92/E93 (2006 - 2013)
    Hello, I have a e90 that I recently purchased. When I bought the car , I knew I was going to have a lot of trouble but was optimistic. it has had a misfire on pretty much all cylinders but now is only one 1,4,5. I have changed valve cover gasket, breather hose, coil, plugs , intake gasket, MAF...
  3. E82 / E87 / E88 / F20 1 Series (2008 - 2014)
    Hey guys, I recently replaced my spark plugs (NGK iridium), ignition coils (Delphi), and valve cover/gasket (OEM). After the job, I fired up the car and experienced a rough idle and more engine codes (list below). I have tried removing/reinstalling the coils, but no dice. What could be wrong...
  4. E36 (1991 - 1999)
    I have two codes: P0130 and P0100, relating to the O2 sensor and the MAF. I took my 1996 318i in to get smoke tested cause its stalling at idle. When I let it idle on start up, its fine but after 10 minutes, the rpms drop and it starts misfiring and sometimes stalling. I replaced multiple vacuum...

    2012 e71 x50i Scanned codes after limp mode and found lambda errors, cleared and drove fine then another day after hard acceleration and limp mode found errors for misfire cyl 1 and 2.

  6. F10 / F11 (2011 - 2016)
    Hello All, 2013 535i w/ 59k miles. Original spark plugs, injectors, & ignition coils. CEL came on, pulled codes to see that there is some misfiring going on. I'll start with my question and then explain the situation. Question: how do I determine which component is bad? Is there a way to...

    Hello everyone, another problem came up on my shitbox e39 I took it out for a drive after changing crankshaft sensor and after banging some gears I got like 12 codes with terrible misfires, some of the codes were camshaft sensor circuit stuff, crankshaft short circuit, ignition coil 5, 2 short...
  8. E63 / E64 6 Series (2004 - 2010)
    Hi guys (2005 645ci) so last week I went to start my car in the morning rough idle/hesitation when it started then received “increased emissions” on the dash. Brought it to my mechanic and it read off: P0300 random/multiple misfire P0302 P0307 P0308 reset the codes the rest of the day seemed...
  9. E36 (1991 - 1999)
    I bought my manual 1996 318i (M44 engine) less than a month ago and immediately started to have problems with it having a rough idle. The idle was super violent, shaking the whole car, and sometimes stalling after revving it and/or coasting to a stop in neutral. I replaced a bunch of vacuum...
  10. E90/E91/E92/E93 (2006 - 2013)
    I have an 09 E92 N51. Long story short, I was attempting to diagnose a misfire on Cyl #6 and alot of people on different forums said they had no misfire when the ESS was unplugged. So, in my infinite dumbness, I did that, and the engine made a very loud noise and spit out a P0016 code along with...
  11. E36 (1991 - 1999)
    So I made a post here a few days ago but this one is an update. I purchased a manual 96' 318i convertible (m44 engine), and it's had a super rough idle since I've had it. It sounds like it's cammed and it's a rhythmic feeling like a misfire. I don't have any codes popping up other than P0130...
  12. E39 (1997 - 2003)
    2003 530i Auto Sport, 140K miles. One day running fine. Next morning, it was like running on 3 cylinders. Parked it and have been driving the 540 for about 4 months. Last weekend I decided to take a look. Read codes and got cyls 2 and 4 misfire with fuel cutoff. I thought that was interesting...
  13. E46 (1999 - 2006)
    Hi, I have a 2003 e46 with N42B20A engine that's been acting up for quite a while now. It started misfiring on idle and low rpm (1-2k) last spring. Took it to the shop this summer where they changed all plugs, one ignition coil and the timing chain and thought it was fixed but it wasn't. The...
  14. E39 (1997 - 2003)
    Hello, My dad and I serviced my 1999 E39 523i with an oil change and new spark plugs on the 16th. Both the old and new plugs are NGK BKR6EQUP. I drove home without any issues after that. I then went on a 70 km drive the next day with a few minor stops but after roughly 65 km the car started...
  15. E46 (1999 - 2006)
    Hey everyone! I've compiled all of my currently present problems on my 2001 318ti engine in this one post, hoping maybe one problem will help with diagnosing the other. So here are all of them: 1) Engine occasionally revs up to 1700RPM and then instantly drops down to normal (700-750). It...
  16. E90/E91/E92/E93 (2006 - 2013)
    Hey guys, sorry this is a long one but I'm completely stumped along with a shop and have tried everything, about 3 months ago i decided to pull the trigger on a 07 335i E90 and starting to think it was the worst mistake I've made, at first the car was just not making any boost, and consistently...
  17. E82 / E87 / E88 / F20 1 Series (2008 - 2014)
    I am currently having a misfire or sometimes there is an hesitation in my engine that will eventually clear if I keep slowly giving it gas. I have brand new Ignition coils, switched out my low pressure fuel sensor. However when i changed my spark plugs, this issue went away for a day. Everything...
  18. E60 / E61 (2004 - 2010)
    Dear forum members I recently bought an E60 550i with the n62 engine. The car feels good and the engine sounds good and it idles steadily. However, I have encountered a very strange behavior when I push the throttle when cruising at around 70 km/h (44 mph). When I push the throttle rather...
  19. E90/E91/E92/E93 (2006 - 2013)
    Good day everyone, I'm currently having an issue with my 2008 335i 6MT. I'm experiencing a misfire after replacing my injectors. Car has new Index 12's on all six cylinders. Coils and plugs were done in May 2022 and are OEM Bosch units. Car is completely stock besides BMS cone intakes, a...
  20. X5 E70 (2007 - 2013)
    I'm going to apologize ahead of time because this will be a long post but I want to provide all information that I can to help understand the situation. I bought a 2007 E70 X5 with the 4.8 N62 engine with 100,000 miles back in November. The previous owner was a small car lot. They said they...
