Correct.

Or maybe the store wanted you to buy 4 and then use two and send me two.

Good luck.

There are two. For some reason all the parts stores think our cars are OBD II which has 4.

I just replaced mine a year ago (1995 GT) and it came from the factory with four, two before the cats and two after the cats.

Where exactly does it say they have 4?

We have 2. The reason cars have 4 O2 sensors is because OBD II cars read after the cats too, to make sure they are working properly. OBD I (our cars) do not.

If we have 4 O2 sensors then everyone else on this site has been wrong about it as long as I have been here, or maybe you have a 96+ midpipe.

There are 2 cats and four O2 sensors. Walker still sells the sensors as up and down stream, one left upstream, one left down stream, one right upstream and one right down stream.

There are definitely 4 cats and two O2 sensors. I have my stock H-pipe at my dads if you want me to prove it.

If you really did have 2 cats and 4 sensors then that is definitely not stock.

Read through these threads. We have 2.

If someone thinks they have 4 O2's, buy four O2's and see if a place to put them can be found.
