Well I decided since I was not getting results checking the duty cycle I would check the voltage between pins 3 and 2, it stayed right around 0.64 - 0.65! Then decided to check 02 voltage warm (since the car was already warm), and its putting out just over 0.9V! Turned it off for awhile started it back up and it was at .899. I will try it again tomorrow when the engine is cold. If I check the voltage between pins 3 and 2 with the O2 unplugged it right around .4 So either the system is running really really really rich (thought these only went from .02-.08) Or my O2 is faulty, what do you think?

I am going to hold off adjusting the air/fuel screw until I get an accurate duty cycle reading. I noticed my alternator is not putting out as much juice as it should, it's only maintaining 11.7 volts. Guess its time for a new alternator or voltage regulator. After I get the charging system back to what it should be I will go ahead and retest the O2 and duty cycle.
