[16v] Bad O2 sensor symptoms?

[doubt at inwave.com (Nate Mellom)]

Cathy,
I saw the setup you had in Cincy, I assume that's what you're talking 
about for checking the DPR?  Unfortunately, the one Bentley I don't have 
is the one for this car (I have the .pdf, but not the paper version 
yet), so any hands-on help would be great!
Thanks!
Nate
