if bank 2 is showing rich your comp. will try to lean out that bank/ meaning your plugs will show lean. if it was your cat it would show up as a cat/efficency below treshhold, but that would be your down stream o2. may be aleaky ijector, pull out all plugs, see if one is shoowng richer than others.
