I had a bad o2 sensor when I got my car. I replaced that, and I use my datalogger w/ MMCD a lot. Usually at idle, I can see the o2's go from rich to lean, etc etc. Now at idle on MMCD it shows just .01V, or .03V. I get o2 readings when I'm flooring it, just not at idle. The wire connectors are fine. Any suggestions? WTF
 
persionally i would say that the sensor is getting bad or the heater on it is going bad in it because it dosent sound like it is staying worm enough at idle becasue when at WOT or whare ever the egt is higher but even then is it still getting an accurat reading. but good luck i hope this is helpfull. :dsm:
 
Yeah I let it warm up. Well as long as WOT is still accurate, the idle will not bother me. Thanks.
