If you are having better luck with your O2 unplugged, you might consider replacing it. I do not know if the SC use a one, two, or three (heated) wire O2, however, I can offer a bit of insight: An O2 sensor is an O2 sensor so long as the replacement has the same number of wires. My Turbo Buick had a single wire O2 and it cost about $35 to replace. My 88 944 Turbo had a three wire O2 and it cost almost $250 (i think - been a while) Anywho, looking at the sensor for the 944 Turbo, I noticed it was the EXACT SAME three wire as I have seen on the Ford trucks, the only difference being the connector that plugs the sensor to the harness. Being the kind that loves to foil retail gimmicks at every opportunity, I bought a three wire FORD O2 sensor, cut off the connector, removed my old 944 sensor and cut off its connector and spliced it on the FORD O2. The car ran great for more than a year of hard driving like that.
The point here is: don't let cost keep you from upgrading your O2 sensor. They do a pretty darn good job of keeping fuel consumption in check and when in good condition will keep your car running happily for many miles.
