I waited until T-stat opened and took the following readings from my O2S:

Connected - ~0.18 volts
Disconnected - 0.00

This sensor is in the exhaust manifold. I also had a fairly new bosch sensor in the straight pipe (pulled it off my 93 before I scrapped it) and that one gave me readings around 0.21 (plugged in or disconnected didn't seem to affect the reading). So I guess I need an O2 sensor, but I'm wondering if I didn't wait long enough to get accurate readings considering both sensors didn't give fluctuating signals?
