Might not be the answer...but on the F-body the MAF and 02's (couple more things for M6) are on the same ENG SEN fuse circuit. If yours is the same something easy to check first.

On F-bodies ENG SEN = Engine Sensor. Look at the fuse into in your owners manual, should list everything on the circuit if it's there. Ours is under the hood.

air filter
Make sure your air filter is clean. I have Volant intake with K&N's and had the same codes popping. My car however was not running too bad. I cleaned the filters and the code disappeared (for now). Just a suggestion
