I replaced the secondary air MAF Sensor but am still getting the P1411. I can hear the Secondary Air Pump kick on each morning for less than 30 seconds, I read it should run for 3 minutes. Not sure if that is a problem or not. If I keep my foot out of it and don't let the RPM's go past the 3800 to 4000 rang it runs ok. No low end power but gets me from A to B. When I do go over the 4000 RPM, or put too much of a load on, the engine starts misfiring and the MIL comes on. Once stopped it runs very rough, and sometimes stalls. I turn the key off and start the engine again, and the MIL goes off and is running smooth just as it did before the misfires. This routine goes on all day every day. Occasionally I can drive all day without a MIL coming on, but upon start up the next day it comes right on. I'm getting P1411, P0153, and P0174. Also Misfire codes for Cylinders 1,2,and 3. Also I have replaced 3 out of the 4 O2 Sensors, (BOSCH) I wonder what the correlation is between Slow response Bank 2 sensor 1, and Misfires in Cylinders 1,2, and 3. The only O2 sensor left to change is the bank 1 sensor 1 and there doesn't seem to be anything wrong with that one, but this is coming from a guy who is learning as I go. Can anyone help me solve this problem?

Unfortunately I haven't had that problem before. Let me check a national database of repairs to see if I can find something that can help you. What model and year is your vehicle?

2004 325i E46 with the M56 Engine. (It's the SULEV model. Never again!)
