The front O2 sensors should fluctuate rapidly between 0 and about 700-900 ( it's been a while since I've made a log) mV. The plugs for the front and rear O2's are the same, it's the ECM that reads them differently. If you're worried about the "performance" then make sure the newer O2 sensors are plugged into the front, and the older ones are plugged into the rear, since the rears aren't really important from a performance standpoint.
