O2 Bank 1 .80 Bank 2 1.0- Only at idle and warm
My post 02's are reading .8 on Bank 1 and 1.0 on bank 2 at idle only.
On load they are 1:1.
Brand new O2's, injectors tested and recalibrated, fuel pressure regulator set to 3.8. No vacuum or boost leaks.
The issue only shows at Idle. The problem only shows face once it warms up.
Thought it was a shot in the dark if anyone had an idea?

I've had / seen this issue aswell. I would reset your ecu, and then let it learn again and see what happens.
Is your fuel setup in one rail and out the other? Or split and into both and then out. I've always wondered if to much fuel flow at idle was causing and imbalance in fuel pressure at the rails.

I would start by swapping 02s around... was it like that from the start or it happened recently...

If that was the case you would see issues on both sides i would assume.
I will give it a shot thanks.

Reason I asked is I got some weird readings after a few "slush" runs and when I dried it all out the next week it was normal..
