Grounding A/F sensor?

After putting in a new O2 sensor a couple weeks ago, I noticed my A/F gauge was still reading rich (I normally have it stashed away until I get my pillar pod in). The last two days, it'* just been on full rich all the time. So I yanked the signal wire last night, and the reading didn't change. I'm thinking it was grounding out and affecting my O2 signal. I got on it a couple times on the way to work today and I didn't see my characteristic light smoke puff in the mirror.
