WOW. Where do all of you people LIVE?!?
I recently had to remove 2 oxygen sensors from a pair of 87's- one had
been sitting in a field of tall grass for years, and the other was
driven in the snow all the time. I used whatever wrench it is that fits
(7/8"?) and just... unscrewed them. No penetrant, heat, or anything.

Amazed,
Simon
