My cars SES light came on. Got it scanned at autozone. They said bad O2 sensor on the rear, right bank. Car was runnin a little goofy, then we got a killer rainstorm. After I drove a wile the SES light went out. Car is running great now, better than when light was on for sure. What do you guys think? Should I still get a new sensor or let it go? Thanks,

Your rear o2 sensor should only monitor the cats performance and has nothing to do with how the engine operates, it would through a code if the reading is of or the sensor is bad but wouldn't affect engine performance at all.

That is what I thought, but that's not the case. I am not sure exactly what happened in that rainstorm. Maybe something dirty got cleaned, and now works. I dunno, got me by the jolly danglers. Thanks anyway.
