Re: o2 sensor removal

I replace the ones on my wife’s '92 GM using the special O2 sensor socket and using a universal joint on the socket. Even with the universal it was a pain to remove them and put the new ones back in. It can be done with patients.

I only know of the two just in front of the firewall.
