How to remove a stripped oxygen sensor from my 05”??

i’ve soaked it for a few days in PB Blaster,
heated it with Map has, stripped or snapped two different styles of O2 sockets, ended up using vise grips as a last resort tightening them at the verge of a brain hemorrhage then using a dead blow hammer and no luck…

next???

05” special value with 156000.00 miles, original O2 sensors.

Oxy acetylene torch is your friend at this point. The bung probably needs to be a nice dull red to let loose of the O2. If you don’t have access to one, it may be in your best interest to take it to a shop. Living in the rust belt definitely has its down side sometimes.
