AFR difference between bank 1 and bank 2
At 5000 RPM in neutral, bank 1 (driver side) and bank 2 show different AFR and it's almost 1.0 difference. I haven't data logged yet, but is it ok?
thats what I was thinking.

What I think you have is a lazy O2 sensor on bank 2
that is starting to give up!
Check your data logs and see if the ecm is adjusting the A/F
corrections at nearly the same time. you might find that bank 2 stays longer at one value as bank one is moving around to keep it at 14.7.
Correct me if I am wrong.
