So my question is this: How the hell do I stop my car running so rich? Do I need to buy another O2 sensor
You Said it yourself, you took the 02 sensor out, take out your wideband and reinstall the 02 sensor, problem solved.

Then take your car to a exhaust shop and get them to install a 02 bung (believe that's what its called) in close area to the 02 sensor
on the exhaust. then screw your wideband sensor in to there..

From there you will have both sensors installed 02 for the car and wideband for the gauge
