I was always under the impression that when O2s fail they fail lean? Causing the pcm to add fuel (blm above 128 for safety). They are switching but they have been moved I think so may need to tune for o2 delay and such.

either way it’s at 108; -16%, soon as CL kicks in.

i believe it’s false because throttle response become immediate trash but if I force open loop and clear blms the throttle response is snappy.
