    Hey guys - I created this account specifically to get help with my E46... 2001 325XI with approx 298,000 km (185,000 mi) Was running fine up until today and it threw a CEL, started vibrating and running really rough, and had a hard time accelerating, almost as if it went into limp mode. Checked...

    Jump to the most recent post. Car cranks now, but misfires a lot. Hi guys, my 2002 330i 137k, cranks but won't start. Here's a list of events that have transpired so far: -Brought my running car to my dad's place to replace the CCV, since I thought it was leaking oil. I had already changed the...

    Car has been down for about a week now (this is my daily), due to it running incredibly rough, multiple misfires, and stalls out on me. It also has a very loud, slow, random knocking sound from the DISA valve area, inside of the manifold. I had lean codes for bank 1 & 2 (as in all cylinders are...

    Hello, so i have a 2003 325ci and I’ve been having a lot of misfire issues, I’ve replaced the injectors, spark plugs, coil packs, vaccum lines, intake boots, and maf sensor. And it’s still going on. My car will run alright but feels like a loss of power, little bit of hesitation when...

    Hi all, First-time poster, long-time reader. I'm having some issues with my 330ci (2003 reg). I'm currently pulling the codes P1345, P1351, and P0300. The car starts, runs, and drives fine, as long as I don't let it idle. If I leave the car idling for ~10 secs, whether that be hot or cold, it...

    2000 328ci. Has anyone else had this issue? I’ve been dealing with it forever and it’s driving me crazy. I have replaced my purge valve which is what my CEL was from but it didn’t change my issue. It starts decently in the morning when it’s cold but if I drive it for a bit and park it, let it...

    I have a bad misfire on cylinder 2, Ive replaced my spark plugs again just last night. I swapped a known good ignition coil from cylinder 1 to cylinder 2 and the code didn't change from P0302 to P0301. I even did the test where you unplug the coils while it's running and each cylinder except no...

    So let me get straight to the point, had a great day driving and as soon as I get on the road home, really bad misfires started happening. It really wanted to stall. I made it to a gas station and it stalled and didn’t wanna crank so I unplugged the maf and it turnt back on. I go home as soon as...

    Car misfires when cold starting starts up and shakes like an old v8, just fixed loads of vacuum leaks (intake, ccv, disa) it goes away and runs fine after a minute or so then drives perfectly fine (barring awful mpg when accelerating even if very gently) only seems to do it when sat still for...

    To preface this, I have re-done the PCV, replaced almost all of the vacuum lines, replaced intake gaskets, changed fuel filter, oil changed, intake boots, replaced the crankshaft sensor, changed spark plugs, replaced DISA, and even cleaned the injectors. Even though I have done all of these, the...

    Hello, I have just purchased my first BMW (03 325ci manual) and it won't stay running. It will only start after I leave it sitting for a while, and when it will start, the throttle response is super delayed and very vague. I plugged in my OBD2 scanner and its giving me the following codes...

    I'm trying to resolve some issues with my 2004 325Ci with 192k miles. It has been getting progressively worse, goes into limp mode if I exceed 1/2 throttle and 3k rpm. Maintenance has been neglected on this car for a while, that's how I got it cheap. I've replaced plugs, coils, front O2 sensors...

    Hello all, I ran into a huge problem today and can not drive my only car anymore. I started the car today and actually felt and heard the misfiring once I put the car into drive. The car then shut off after moving a bit and I was able to start it up and move it back, still misfiring. Scan and I...

    Just picked up a 2000 323i and I don’t know much about bmws, it’s throwing codes for a misfire on 4,5,6 and a few other things (in the picture) I’m not sure what’s going on, eml will go on ever now and then and go into limp mode and if I turn the car off and back on it will go back to just a...

    I turn my 2001 325i idles at 750 slowly dropping as it warms up has a rattle that I think is the exhaust lifted the car up and it is welded and hanging and mangled. Muffler bounces hella.Once it gets down to 500 rpm not fully warmed up yet the rpm goes down kinda hesitating and sometimes it does...

    Okay so I have a 2000 323ci with 208XXX km's & I have been chasing misfires and codes for 2 months now. I have taken it to two indy mechanics and have replaced/fixed a bunch of parts and leaks, but I keep running into the same code... Cylinder #3 misfire (plus an intermittent #6 misfire but its...

    My 2001 330i has not been running good for quite some time. I’ve had random codes for misfires, one for my disa even (p1512) my camshaft position sensor (forgot code, will find if necessary) and a lean code. Now my first thought was a vacuum leak, but I’ve smoke tested it multiple times, and it...

    Hello guys! I have one question? I have a problem with the ignition of the 5th cylinder when the engine is cold. I replaced the spark plug, coils, petrol filter, and one air hose after the flow meter. Any guys with the same problem like me.

    So i’ve had this car for almost a year now, and it’s still eating me alive that I haven’t this problem out yet. I’ve posted about before but I feel like I was not looking in the right direction and i’m still not 100% sure but I feel like i’m closer. To give a little detail this problem only...

    Hi recently my CEL went on for cylinder 2 misfire P0302 and a fuel trim bank 1 code. idles shaky / rough, bad response, loss of power. Did spark plugs today and while the old ones were definitely worn and old, the new plugs did not fix the misfire. Im thinking I replace injectors next? or...
