BMW 325Ci Misfiring

[BimBimerBoi]

Hi there, purchased a 2001 E46 325Ci the other week and have been driving it since, not even owned it a month yet and unfortunately I have developed a couple issues.

The main problem I have now is that it developed a misfire :’( ... It happened the other day but I managed to get it back fine, if I let off the throttle then some times it would cut out but would start again on the starter. I got to the car the following morning and it drove to work fine at which point I noticed the engine light had gone off.

Engine light came back on today and started to misfire again so I threw the OBD on today and it threw 9 codes. A couple was about it running lean (because previous owner fitted a pod filter, air box on the way) but they aren’t much of a worry. All error codes photographed in an album below.

If anyone knows of this problem and or knows what I could do to remedy it then please let me know, also the cars at 136k miles if that helps any more info then just ask.

Sounds like a fueling issue.. pump ok ? I was going to say a coil but on all cylinders like that I doubt it. Cps will cause issue also.. maf or airbox won't be causing this

Running lean wont be an induction kit /or cone filter more likely a split intake lower boot or crankcase ventilation hoses failure on your M54 engine
