			I have a 01 325I which is displaying the codes listed above.  If I'm correct, it has to do with fuel cutting off on cylinder # 1,4,3, and 5.  Prior to this the car wouldn't start and I had the fuel pump replaced, but now it runs rough only after I hit 50 mph.  any ideas?  thanks

			I am speculating but it is likely a sensor that effects fuel ratio such as O2 or MAF.  Could also be a intake leak after the MAF sensor.

			Do you have any strange noises? Since it is above 50 you should check the intake tube after the MAF.

			no noises as I remember.  Should I be looking for cracks in the tube?

			Yes you will probably want to take the tube off and check it. Did you also replace the fuel filter? This is an E46 with the pressure regulator built into the filter?
