Same, check fuses and wires, and be sure to put some di-electric grease inside the plug when you're re-connecting the harness.

Alternate option would be to put an extension before the sensor to reduce the chance of fouling. ZZP and many other place have them.

Thanks guys. I will check all the wiring and the plug at the O2 sensor. I will use some Di-electric grease on it too.
I'll chek back in after I do those things, but it may be awhile with this damn Chinese Virus bs going on.....
What a nightmare scenario for all of us..... I am hoping it's more media hyoe than reality for 90% of the country and world !
