Eric,  I have been wondering about the O2 sensor on my 90 Spider and if it is 
working properly or not.   I would like to test it, but am not sure exactly 
how to do it.   I am guessing that I should disconnect the sensor at the plug 
and measure the voltage with the car warm and running.  Correct?   Also, what 
do you mean it should switch between .2 and .8 volts?

Thanks,

Nick,
Based on what you sent, and assuming that your 1 year old sensor is still 
good, it appears that your catalyst is pretty much dead.  

Before changing, though, do make sure the O2 sensor is working properly- when 
its warm, it should switch between .2 and .8 or so Volts.  If its not working 
as intended, even a new catalyst won't help.
