2004 X5 Fault Codes P0171, P0174, P0300, P0301, P0302, P0304, P0305, P0306
Does anyone have any other idea's (if anything) that would set these code's. The P0171, & P0174 come up first & then within a few miles the rest of the fault code's show up. I have ordered the new y-duct. Thanks you in advance. Jay <!-- / message --> |

Those look like lean codes to me. Does check engine light come on? I would think replacing the air duct should do it for ya. You might make sure you check all your vacuum hoses too. Same type of problem I had in the past. The above is what worked for me.

Was this reply in the wrong thread? The OP has a 3.0i with the common air duct tear to the idle control valve... As for his random cylinder missfires registered in all cylinders, hopefully it is related.

Yes the engine light does come on. I am still waiting for the new y-duct. Thanks to all for the advice.

When you get the y duct replaced, I think you will be alright. That is most likely related to the miss fire codes. It was in my case as well.

Report back after you've replaced the Y duct. I'd also suggest to reset the codes and/or remove tha battery cables and touch them together overnight as a poorman's way to make the ECU relearn itself. After a couple days of driving, if you've still got a CEL, then it might be time for another visual inspection or a simple smoke machine test...leaks can sometimes be hard to find w/ the naked eye.
