Re: quick question about o2 sensor
The engine needs the O2 sensor. The (primary) O2 sensor provides a critical input to the ECU to ensure that the engine runs on the optimal air-fuel ratio rather than too rich or too lean.

Re: quick question about o2 sensor
its your secondary source for calculating fuel trims. If you have chipped ecu it could be disabled already, I would put it back if you running stock ecu
