Maybe do a visual check on the wiring going to the O2 sensor(s), to see if anything got chafed or pinched.

Wiggle some plugs and cables and stuff around to see if the problem goes away/reappears.

Do a visual check on your grounds as well.

I know the O2 is very sensitive when it comes to voltage, so might as well rule the basic checks out in case it's an electrical issue.
