it's headswapped, no tune. CEL came on about 5 days after the headswap with it running rich in bank 2...

...but shouldnt i be running lean? this doesnt make sense to me. could an O2 sensor be going bad? i know i took the one out of bank 1's exhaust and cleaned it some, not 2's. how could it be rich, and how could it be on one side? can anyone help me out here?
