Bad O2 Sensors

What would be the result of inoperable O2 sensors on spray? Mine were plugged in to the wrong socket (rear v. front), and it seemed like I lost a lot of power.

Thanks!

I don't have rear sensors either, but I was thinking about the front ones. What compensation does the PCM make for them not working and how would that affect spraying?

Everytime I would spray with a bad front 02 sensor it would run extremely rich. It would also have a hard time idling when I would return from a pass. I don't run rear 02 sensors. Texas Speed tuned my compter to eliminate them.
