I was able to break it loose renting an O2 sensor socket set from NAPA, and
I only learned that the bung was slightly oval.  Or the O2 sensor was oval,
but probably both.

It would turn back and forth about 1/8", and that was it.

A long enough bar might work, but if not a new bung and sensor is the fix.
Any good muffler shop will have the bung, but it's best for you to bring the
sensor.  See www.rockauto.com.  $53 for the Bosch OE sensor.

Wow! You just reminded me about the 22 mm extended socket I bought 4 years
ago just to remove the O2 sensor. I used this on my old 2.1 wbx engine. I
had to cut the wires next to the sensor then used the socket and a long
bracket bar. Worked great!
To many tools I guess and an lost in space mind. Lol
I'll try it when I get back.

wrenches . Everything is rusted together. The catalytic converter is only
about a year old. Is there a better way to remove the sensor? Should I use
my touch to heat the sensor ? Any ideas would be great. I might get to
Quebec yet just have to get this done.
