Anybody out there running a heated O2 sensor? If so, did it make your car idle better? I put a heated O2 in my car, and it seems like the car runs smoother at idle and light throttle when I unplug the heater. It also seems like my car has a rougher idle and more vacuum fluctuations when I use the heated O2. Anybody else see that in their car?

Seems that the good ol' 87 did idle a bit better after the heated o2. Just slightly though. The main thing noticed was the longer, more consistant life. The regular ones would seem to degrade fast, and partial throttle ping would result. I installed only one heated o2, and it is still in there after 20k miles and works fine.
