Also there may be a light misfire condition or an injector issue.

will do that i'll swapp sensors to see if the problem shifts to bank 1 or stays the same.

I believe there's a fused heater in one of the O2 sensors. I think it's the post Cat one. They have been known to blow and it's a cheap/easy fix if it's just the fuse.
