O2 Sensor Unplug

[jabb]

Ok how do I unplug the o2 sensor I found the 2 white leads and unpluged them but can not get the black lead to unplug....
is it a screw on under the rubber boot ??? do not want to break anything.....

The white lead are just the wires to preheat the O2 sensor faster. You don't need to unplug them if you are just doing some tests. The black lead is the main sensor wire, and it just unplug by pulling it at the tail section of the black rubber boot. It's a little tricky, because the rubber boot has an internal rib which grips around a groove on the plastic plug.
