You'd prolly want to look for an exhaust leak ahead of the O2 sensors, sorry I wasn't more clear...

Great success! The car was running rich in the right bank because I had the O2 sensors crossed and it died and wouldnt start because the grounding wire on the back of the drivers side head had worked lose. Swapped the O2 sensors, tightened the grounding wire, it fires right up. After 10 minutes, it was idling perfectly with no problems and no hot cats.

O2 sensors are not made to work on either side?? I ordered two new ones and didnt say anything about being drivers or passenger side

Glad it's fixed. Figuring that kinda stuff out and getting the car running tip top is a good feeling.

The O2 sensors can be used on either side, the problem was that I had the electical connections crossed, so I had the sensor on the drivers side plugged into the passenger side harness, and vice versa. The computer wasnt a big fan!
