Stuck O2 Sensor
 

Yet again i am trying to get my stang passed this high 14 second sticking poing...I cant get one of the O2 sensors off to change it...I tried every wrench and socket and breaker bar....the thing is all dented up now from me banging on it and it is just starting to strip... When i drive it around the check engine light doesnt come one or anything like that so i assume it still works. How do i get this thing out, can i just torch it and try to take it out when it is glowing red???

If you are replacing it, you can torch it. Otherwise, keep soaking it with WD-40.

Take care,
