I figured you must have. O2 sensors are cheap. If nothing else, eyeball the O2 plugs.

I had the same issue, random as well. Turned out that the plug on the pass side O2 somehow broke it's zip tie and was resting against the header collector. Melted, exposed wires occasionally throwing the same codes.
