    My '02 330CI has been having a weird issue the last few weeks where it'll randomly start idling extremely roughly and the car will begin to shake. Sometimes the RPMs dip so low I'm afraid the car's about to die. However, if I turn the car off and back on, it'll start to run normally again for a...

    Started my car today and it almost loped. It was way louder than usual and shaking like crazy. After a few seconds of it running, I saw it had an SES light. The codes are as follows: P1083 (Fuel Control Limit Mixture too Lean; Bank 1 Sensor 1) P1085 (Fuel Control Limit Mixture too Lean; Bank 2...

    Hi everyone, so these are the codes currently showing on my reader. Back in April this year I add these codes along with a P0170 and P0171. There was a very obvious misfire that you could feel and hear as well as a knocking sound coming from under the hood. In an effort to fix these codes I...

    My BMW started running rough a little bit ago and started out with a p1512 disa valve low circuit voltage along with like one or two misfires with fuel cut off. This was about a week after I flashed a ews deleted ms430056 on my car if that has anything to do with it. It was a weird problem that...

    Hello! About the car 136hp made in 2000 had the vp44 pump swapped by the previous owner. I removed the EGR completly (bypassed). Swapped pressure converter numerous times (still bad performance) new vacuum hose, cleaned maf also disconnected maf and cleaned breather also no CEL. One moment to...

    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...

    Hello, I have a 99 323i M52TU that misfires consistently at high RPM. The car also seems to have very inconsistent power. Some days I can barely rev out the engine to 6900 (car is tuned for that) and some days I have waaaaay more power. When the car is running good, I can redline as much as I...

    I know, I know that there are countless threads for misfires but this seems a bit trickier. Ive read and read and read and for some reason i'm still dealing with this issue. I've brought it to a couple shops and it seems like i'm not getting any answers. Just recommended things to replace that...

    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...

    Got a real doozy for y'all. I got 15 codes. A couple are trans codes, as I am working on the transmission, and have the harness disconnected. One is an o2 sensor code. (Replacing them this weekend) The other codes are Misfire/Fuel Cut-Off codes. They're attached below. I'm suspecting fuel...

    My friend owns a 2005 325i that had 3 misfires last week, he replaced the ignition coils and it resolved the issue. Yesterday he got the same 3 misfires. The spark plugs looked good and were recently replaced. I was just curious what might be causing this and how we might be able to fix it. Is...

    I have a 2004 bmw 320cd with 150k miles on the clock. While pulling away from standstill the car seemed to hesitate / misfire / judder somewhere between roughly 1200-2000rpm. At first i thought it might be a flywheel problem but then noticed it seemed like a strange misfire. If i carefully...

    So a couple days ago i changed my pre cat o2 sensors in my 2001 320i as the bank 2 sensor threw a code and I figured id just replace both. However, the next day i went on a little road trip and noticed that throttle response wasnt nearly what it used to be and it just feels more sluggish...

    Hi all I’ve got a 2002 e46 330i M54 which since I got it this time last year has been great until recently where I’ve been dealing with an ongoing lean fuel error for the past few weeks (I suspect it’s been around since I bought the car last year, but only just started getting engine light on)...

    Can someone help me understand how I can drive for 10 or more or less miles before I get a misfire. Wouldn't this happen as soon as u start the car. How can it be at different times or sometimes not at all?

    Hi guys, I have a 2001 e46 325ci with an m52tub28 engine (don't ask, old owner had if fitted as it was lower mileage). To add some context I've been overseas for the last 14 months and while away I got my brother to start it and warm it for me every so often. He doesn't have a licence so never...
