Clean your AFM with some CO contact cleaner and reset your ecu

+1 on cleaning the air flow meter.
Failing that, get a compression test. Gen2 2.5s are known for doing head gaskets (my fiance's Gen2 Bilstein did one, as did her friend's Bilstein)

Pro Tip: You can also use Brake Cleaner to clean AFM, as it leaves no oily residue once blown off with compressed air.

The O2 code is probably due to the dodgy AFM. This causes the ECU to fuel the engine incorrectly and freaks out the O2. (too rich or lean)
If I told you I was a compulsive liar, would you believe me?
