Oxygen sensor issue?
Trouble codes say bank 1 sensor 1 and bank 2 sensor 1 heater circuit issue.. Check engine light comes on about 10 minutes after a cold start, I can turn it off and it will stay off until the next cold start.. Seems to be running fine though. Should I just replace the 02 sensors before the cats?

No changes, stock exhaust though I did just have some work done that required removing the exhaust(by a very competent mechanic)

02 sensors
There is a fuse that supplies power to the heater circuit also. It is fuse number 15 in the underhood fuse box. Check this as well along with the melted wiring issue mentioned in the previous post. Good luck with your repair.

Fuse is good , checked it first.. I'll check the wires when I get a chance to get under it
