Yes you busted the bubble.

I now sprayed MD 40. FOr the last one hr struggling to unscrew the old one with a specialized o2 sensor socket.

Any tips or help is appreciated.

Thanks,

Go get something called PB Blaster. I have seen it in auto parts stores and hardware stores. WD40 really won't do a thing there, but PB Blaster works like a charm. You have to let the area soak for a bit in it (i.e. spray and let it sit for a bit).

Check the fuse before you replace the sensor. Drivers side, under the hood. One of the three closest fuses to the driver compartment.
