Question Replaced two Air/Fuel sensors...

[jeryjon]

The bank 1 was piece of cake. The bank 2, first it wouldn't come out and I had to turn it back and forth until it came loose. It stripped all of the treads off the sensor and I looked in the hole, it some of the threads left but then I couldn't get the thread chaser started. Does anyone have any ideas?

I assume yu used a rust buster spray fluid like PB Blaster.

If yu didn't, that was the first mistake.

I would reinstall the new sensor one using an anti-seize compound.
