I got this code 0308 (p1168 from the OBDII AutoZone scanner), and I assumed it was the O2 sensor. Here is DB Martin's info:

0308
Diagnostic Trouble Code 0308 points to a problem with the Engine Control Module Closed Loop Logic for the Right Bank. The right cylinder bank is also called the rear bank. It is cylinders 1,3,5.

DTC 0308 is detected when the closed loop control function for the right bank does not operate even when the vehicle conditions meet the criteria (engine at normal operating temperature, etc.). Possible causes include ...
- Harness or connectors (The sensor circuit is open or shorted.)
- a defective Front Heated Oxygen Sensor sensing element.
- a defective Front Heated Oxygen Sensor heater.

I have no idea where to go from here because I just replaced both left and right bank O2 sensors. Has anyone else experienced this same problem? Any suggestions/recommendations??? I am stumped.

You've only checked or replaced 2 of the three items you need to work on.
Now check the wiring harness and connectors.
