What happens when you misfire a cylinder in a jeep?
Heavy misfires will cause the CEL to flash. If you have heavy misfires, and the gas does not burn in the cylinder it can go out the exhaust and through the O2 sensor and Catalytic Converter and can damage them. So your one code for an O2 sensor being High Circuit might just be a symptom of the heavy misfires.

Vacuum leak – If your Grand Cherokee has a vacuum leak, it can be very difficult for it to get the right air/fuel mixture.
