this is a technical question.
Why at fully open throttle the o2 sensor goes rich ?
does it stay rich all time when the throttle is fully open ?.
what about fuel trim? does the computer add fuel or take fuel at fully open throttle?

The computer adds more fuel during acceleration and then reduces it as needed when the load reduces.

Those are all communication errors, mostly concerning body functions. The BCM is incorporated into the TIPM (Totally Integrated Power Module) which is the main fuse box in the engine compartment. This can be access using an enhanced scan tool for diagnosis.
