So, I had the check engine idiot light come on in my E46 330 Ci. I got a reader, checked the codes, and got these back: P0171 (System Too Lean); P0174 (System Too Lean); and P0369 (Camshaft Position Sensor "B" Circuit Intermittent). I'm guessing these are all related, and that the easiest thing will be to change Camshaft Position Sensor "B." Has anyone done this before? How difficult is it, and is there anything special I'll need to have/do in order to take care of the job?

I'm guessing this won't be an overly difficult thing, but I have been wrong (so very wrong) before.

Thanks!
