My Denso O2 sensor purchased from the site above is still
going strong (on my 91 Civic) after 2.3 years, 31k miles.

Absolutely do not get the Bosch. Either Denso or Walker is
most likely the OEM sensor for your car. Don't let the fact
that this part is not coming from an "OEM dealer" throw you.

Borrow an O2 sensor wrench from Autozone. No charge,
overall. I think mine is 22 mm or 7/8-inch.

PB Blaster could not hurt.

Dunno.

That the OEM one from Manchester Honda went bad at 4 years,
40k miles is surprising. You sure you are taking all the
appropriate precautions with these? Getting any kind of gunk
on the probe will foul them, for one.
