    My E46 325i (125k miles) intermittently drops onto 5 cylinders, from tick over or whilst driving. Stopping the engine and restarting will bring it back to 6 cylinders. The engine management light is on. I've fitted new plugs and coil packs, unplugged and reconnected the mass air flow, but still...

    I'd finally got my '91 850 running nice and smooth, so have been happily thinking I could trust it, but today it's started running on only one bank of cylinders. I've occasionally had this symptom before, mainly on starting up, and found if I turned off and cranked engine again, it would fire up...

Upon starting the car it runs fine for anywhere between 1 - 3 minutes before the revs drop, engine shakes and power is lost. At this point, the...
