Mine does the same thing with the O2 sensor unplugged, you need the O2 sensor plugged in to allow lambda system to control the mixture.
Set the idle CO to 0.4-0.8, set the idle speed, reset the CO to 0.4-0.8, then install and plug in the O2 sensor.
When I do this with mine, all my values are about 1/2 to 1/3 of the local limits. I don't have my test printout with me, but our limits are pretty close the California levels, so that's not bad, especially since I have C2 cams.
BTW, if the O2 sensor has been unplugged for quite awhile, it could be toast. I have a dummy (bad sensor) I run between tests just to plug the hole, and save the good sensor for test day.
