Secondary O2 sensors have no bearing on fueling or how the car runs. They are the "rear" two sensors downstream from the catalytic converters - one per bank.
while yes, in theory, you are correct, but ive never seen a sensor cause such havoc. for all intents and purposes, the o2 sensors are mere monitors and even bad ones wont cause fuel trims to change performance, noticeable anyway. but who knows, this car has proven to be a very weird car already in other ways.
