Question about BMW 325Ci
Help with engine codes displayed on OBD tool (no year option). 2003 BMW 325Ci. P1342,P1344,P1347,P1348, & P1350. All of these seem to do w/ misfire during start cylinders 1,2,3,4 & 5?? Also P0300(random multiple cylinder misfire). P0306(possible O2 sensor circuit malfunction Bank 1 Sensor 2)???? And last but not least, P1083(fuel control mixture lean bank 1 sensor 1) & P1085 (same as other), but has to do w/ bank 1 sensor 2???? Should I just push it off the side of a mountain?? Please tell me where to start? HELP??
You might want to start with spark plugs. I'm not sure if that year has coil on plug ignition, but if it doesn't, spark plug wires are probably in order as well. Some of the O2 sensor faults could be caused by the poor ignition your mis-fires are causing. Sensor 1 is closest to the engine, sensor 2 is further away, on the other side of the Catalytic converter.

I'm going to take a guess and say likely to be in the passenger compartment. Sometime, they are near the glove box. You can also look under the driver side compartment. There should be a plastic protective cap. Use a flashlight.

These codes will have to be cleared and the car driven through a drive cycle, maybe a couple of times, is the check engine light off? Also you should check your MAF sensor it may need to be cleaned or replaced and makes sure there are no holes in your intake tubing. Hope this helps, let me know.

Usualy this happens when you have vacuum leak after air flow meter , bad flow meter or temperature sensor.Actually for this problem I would take car to mechanic shop.

What all this codes have in common is that every single one of them can be caused by a vacuum leak, so carefully check for cracked, loose or disconnected vacuum hoses, wiring to the coils, fuel pressure regulator, fuel injectors, specially on cylinder 2.
NOTE:After cylinder cut-out system is turned off, the system monitors (through misfire detection) if all intake and exhaust valves are open again.
NOTE:Misfiring may be caused by many faults in the fuel injection system. Usually a misfiring fault is stored with faults pertaining to other components. An engine mechanical fault could also cause a misfire condition.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.
