Okay, bank 2 sensors have one job they monitor the catalytic converter. They have no control over fuel control that is why you see the 99%.
There is no bank 3 sensor.

Have you had the injectors cleaned? No additives as they have no effect. This is a procedure that disables the fuel pump and uses the pressure test port to add a cleaner that will clean the injectors directly. The engine runs until the cleaner is exhausted and then you can return the system to the fuel pump.
