Hi there

Pulling the plug on your sensor will probably give you a fault. i know why it is there so iv'e never tried it.

taking the whole sensor out of the exhaust will only let it sense the higher concentration of oxygen in the air, the result is the ecu sees it as being too lean because combustion uses oxygen. you may well get over fueling.

Never take out the top sensor. It is There to optimise the gas/airmix. Only the bottom sensor does nothing but tell if your exhaust emission is correct. They are very different sensors.
