My 2 cents worth,
I don't think you could get a lean code on a single cylinder must be bank 2 lean code
You need to look up the exact codes, there is a list of them over on the main contour.org site in the faq section i think. I know its there somewhere as i used a couple months ago.
I would assume the if the maf is reporting less air flow than actual you could go lean. I would imagine bank 2 would run hotter than bank one, since bank 1 gets more airflow but that is just arm chair engineering.
Maybee Terry or one of the other Gurus can jump in here......
