O2 sensor weird issues

[downtoearth1986]

I had a check engine light pop on recently. I replaced the bank 1 sensor 2 O2 which had a clipped wire. All rear downstream O2 are from carparts and NTK brand. Car barely is driven until my off days. Car has sat outside the past several weeks. Today I received the same code and misfire code on my SCT FLASHER. I jacked the car up and now I have the same Passenger rear bank sensor 2 and driver rear sensor 2 with the same issue. Both sensors are secured with enough slack with zip ties. I never had this issue until now and I have always secured things away from the exhaust and provided the proper slack. What could be possibly causing this? Should I change brands or could it be the quality of the wires breaking do to movement?

Maybe a mouse chewed them? Fair to say it's likely being the car sits often.

That looks like it was chewed.
