Is this generally a vacuum leak?
Even while driving, they will dip into the low 100's every now and then.

Pretty normal as the PCM is figuring out where Stoch is. It has to move the fueling around so that the o2's swing.

Isn't this what's referred to as a lazy o2? And do lazy o2's affect performance or is it no bid deal if they don't switch constantly?

Not sure exactly whether what he is describing is normal (I think so) or lazy. Lazy is usually more than 2 seconds of flat line o2 activity.

What mine did was while idling, they dip to zero...cars stumbles with idle and it returns. It even did it while driving it around...02's went to zero...car went lean....and it returned to normal.
We can make a much better decision if you would post a tune & log.
