Not running an oiled pod filter are you?, go to Dick Smiths/Tandy and buy some "contact cleaner" and give your AFM a good squirt, that's where I'd start.

With multible codes.. I'd be thinking that you should replace the Ignition Relay. I know it sounds odd but many a time these have not failed but make the 12v+ power give a not true voltage (due to arcing in the contacts) and in turn causes the ECU to ready lower readings from many different sensors. This is a common problem with many Subies and seen many cars come back to the dealership under warranty with this problem.
