O2 sensor-94 LT1

Hey everyone,

How many O2 sensors are there on a 94 LT1? Easy to get to? Location?
The manual I have isn't clear on the location.

1 on the driver side and 2 on the passenger side. They are side mounted on the exhaust pipe before the cats. And easy to reach from below. If you are replacing them only replace the front two.

We had a big discussion about the 3rd O2 behind the cat , it was designed in as a prelude to OBDII that was not effective until 96. It doesn't matter if that one works right as loing as it is there to plug the hole in the pipe. If you buy a catback exhaust you can delete it.
