what should DMM read at WOT ???

[Stpndsmnn at aol.com]

I picked up a Digital Multi-Meter today and hooked it up to my O2 sensor so I 
could check A/F ratio on the fly.  At idle it averages around .5v which is 
normal/correct I believe,  up to WOT it increases to around .6v - .7v or so.  
At WOT it goes to .01v - .02,  is this what should be happening or is there a 
problem I need to address?  I switched the wires around on the full throttle 
switch and even touched the wires together but it never went to .9v and I am 
thinking it should.  If there is a problem what should I check next?  My car 
is just CIS injection not CIS-e if that matters.

Thanks
