Mine just tipped over 88k and I did them just because they're 15 years old and have 88k on them. It was just recently so hard to tell if fuel economy has improved but it does run a tad smoother.

If you've got the money to do so, by all means. Its always better to do preventative maintenance in my opinion, especially with the age and mileage together.

Being one of the cheapest cost items you can buy for a vette that can have a major effect on engine operation and performance,it just makes good sense to replace them as a maintenance item. 30 to 35 dollars a piece is peanuts. 95 has 3 sensors but only the 2 fwd. sensors are actually needed with the OBD1.

Yup. Cheap peace of mind on the preventive tip. If you accidentally break one of the pigtail connectors (they become brittle from engine and exhaust heat) you can buy them at NAPA Auto Parts stores.

Your '92 has two (one on each pre-cat). They can run anywhere from $15 each at AutoZone for the Bosch to upwards of $60 each for O.E.M. AC/Delco or Denso, depending on where you buy 'em.

I believe one of those numbers is a Delphi number. Not sure which though. The AFS75 is what I run in my '96 if that helps any.

you'd be shocked how many systems are affected on a car by the O2 sensors...fuel, timing, cooling... it's definitely wise money spent!
