P0171 & p0174

CEL came on, car was idling rough and misfiring on all cylinders. Hooked my scanner up and it showed codes P0171 and P0171.

Where should I start for diagnostics? I'm going to replace my fuel filter (not sure if it's the 1 or 2 inlet one, I've seen both on 05 330xi's?). I also don't believe there is any intake leak, but I can check again. Other than that, what else can I do?
