Straying away from my E34 forum to get some advice on an 01 325i.
Not my car, but my friend has asked me to look at it for her. It has stalled a few times, and/or run rough for a bit, and after it does either it trips these codes.
P0300
P0174
P1345
P1347
I know the codes are lean mixture, multiple misfire, and cylinder 2/4 misfire with fuel cut-off.
In the two years she has had the car is has never seen a tune up or anything but oil, and the shop never reset the oil indicator. She had the oil changed yesterday and when i went to look at the car i reset the indicator for her.
Im looking for any ideas as to what could cause this to happen, it is not all the time, a slight jumpy idle, but otherwise runs fine until it runs rough and might try to stall.
Im leaning toward vacuum leak, bad plugs, coils, or a soon to be failed fuel pump.
But since y'all know more common things with this series than i, ill look forward to any advice.
