I am not sure of the Cali cars but the only O2 sensors that I have seen were the one wire sensor. I started working for a local Olds in 1984 and I worked on a lot of these vehicles. Very common problem was the purge valve filling up with raw fuel, easy fix, replace. Why you are at it, check the canister filter at the bottom of the canister. It looks like a small pancake made out of fiberglass. When ever I did a carb overhaul, they got a filter and a purge valve.

Also check the canister thermell switch that threads into the top of the intake manifold, a lot of times the cap is missing and there was a recall on them for some year cars. That was some of my early experience on GM recalls.
