Oxy. Sensor Woes...

["Matt Willey" <mwilley@logical123.net>]

    Well, my fun with my car continues.  But, it appears as if my oxygen
sensor system might be at fault for my car running like crap.  As usual, I
come to the group looking for help.  Ok, so here is the deal.

    I hooked up my dwell meter to the B/W wire on duty cycle test connector,
and the meter ground to ground.  My reading was a very flat 0, absolutely 0.
The car was warmed up, nothing.  Unpluged the oxy thermo switch, nada.  No
matter what I got 0.  Is this possible, and would the car run at all if this
was the case?

    Ok, part 2.  I unplugged the frequency valve.  Oh, with the fuel pump
running, I hear no buzzing from this thing.  Anyway, I hooked up my
voltimeter to the connector for it.  My book says it should have voltage,
well gee, you think.  I get voltage, but only about 100mV, is this right?
Well, thanks for your time, any help is appreciated...

TIA,

Matt
