2004 x5 3.0i and missfire Help
The codes I am getting are secondary-air hot-film air mass sensor, trimming 02 before cat bank 1 and trimming before cat bank 2. I have replaced disa valve, replaced CCV, cleaned Iac "all new gaskets well I was there, new plugs, new mass air flow sensor and had it smoke tested to be sure of no leaks.I also changed fuel filter and verified pressure. I have read numerous thing on this and have tried almost everything, could the secondary mass be part of the trouble? If anyone has a thought please share as I am ready to give up, but am in to deep to stop. |

You are correct, was a cheapo map sensor. Went ahead an ordered the siemans, I did see a lot on that but obviously none of it sunk in, thank you and will give it a shot.
