Hey guys so I’ve got a 2003 330i and I’m having trouble diagnosing what’s wrong with the car. Out of nowhere the car shakes pretty good at idle and has a large loss of power when driving. It threw codes for cylinder 3, 4, and 5 misfire and fuel cut off. I replaced the fuel pump knowing how...

I haven't found any discussions about my current issue... I might've not looked hard enough but i want to talk about the issue i'm having with my current 04 325i M54 engine. There's this odd rattling/buzzing sound when i accelerate above 2000rpms until 4000rpms and then it stops, but as i'm...

I have a 2003 330Ci vert with 193,000 miles (310,603KM) with a rough idle and over all sluggish performance. This mimicked the behavior of my DISA failure but unlike the DISA failure clearing codes doesn't even give a moment of clean idle/running. The issues began today when I went to start my...

Hey guys, Before I bagged on for not searching various for the forums, I can attest that i did search the internet and have not found anything that fits my specific problem to a tee. (possibly I am just misunderstanding what someone else wrote) Any help would be greatly appreciated '00...

Hi all, I have a 2002 330xi. It has been running fine but ever once in a while the service engine soon would come on after filling up with gas. After a couple starts the light would go back out. Yesterday the car took longer to start than normal and the service engine soon light came on. It...

Hello, my 330ci started to randomly idle VERY rough, going from 500-1000 and when i try to accelerate, it is bogged and very slow, and is very jumpy as it is trying to move but can't. The car runs great for about 30 minutes and then randomly starts this issue where the car is almost incapable of...

My car, an 06 ZHP vert, started yesterday with an erratic idle and seemingly a great loss of power...it ran like sh*t. Decided not to drive it and by the time I shut it off, my "Service Engine" light came on. It sat overnight. Tried again this morning, same deal. Light comes on after about a...

Hi I have a BMW E46 2002 318i - Automatic. It's been causing me problems recently where: Car pulls off fine on start and drives fine for most of the time But sometimes, into the journey, starts feeling sluggish and slows right down when off accelerator - like I'm driving with a flat tyre or...

I recently (a week ago) replace my alternator and battery. When I check my volts using the on-board voltmeter I notice it goes up and down. is this normal? :confused: I shot a video with my camera: http://videobam.com/wntJH I also noticed (and this happened only once) at cold start with the...

2000 BMW 330ci Did a 0-100 Km/h test for the first time a few nights ago. Had a passenger using iPhone as stopwatch and half a tank of gas of 98 octane; traction was turned off and steptronic tranny was in manual mode; I took off from idle (didn't hold the gas and the brake before launch like...

I have a 04 325i, with a 5 speed and it has 104k miles on it. When I accelerate from about 2800 to 3000 it is almost like the car is lagging just a little but once I am over 3000 it kicks like a bimmer should! It isn't very violent but its noticable and quite annoying to me. I shift around...

I'm starting a new thread for this issue, since I think it's separate from my rough engine issues that are now pretty much gone. (Yay!) Here are the symptoms: Starting out from a complete stop or from slowly coasting along is sometimes sluggish/not immediately responsive. The car lurches a...

Please HELP!!!So I just got the car a few weeks ago, and havent had any probs until yesterday........my wife thought she had run out of gas. The low gas light had just turned on the night before while pulling in the driveway. When i got to her she said it just died. I put about half a gallon of...
