what air filter are you running?

was the AFM new from Subaru or else where?

I have a diagnostic data scanner.....takes 5 mins to plug in and diagnose dead afm, tps, etc.

O2 sensor only effects cruise mixtures really.

give me a buzz (0401291357) if you'd like me to swing past with the scan tool.
