Anyone knows whats up? Running lean at WOT, B2 o2 reads .0435 CONSTANTLY...(more)

[Blue AWD]

Bank 1 is still running somewhat normal, but bank 2 shows .0435 while cruising, idle, and WOT. Even when B1 is showing 0, B2 is still showing .0435.

Brand new plugs and coilpacks, injectors have about 1k miles on them. New EV14s from VAST. I swapped ICMs with no change.

Also, I am getting code 17704 coolant temp. but it is brand new and my thermostat is stuck open so I think its from that.

Any ideas? 02 sensor? EGTs are coded out. MAF is normal readings. Thanks.

maybe your o2 sensor is shot?

O2 sensor is shot if it gets a constant reading.
