O2 sensors 1223 code resolved

["KARL MAXON" <KLMAXON@worldnet.att.net>]

After a thorough diagnosis at the shop (Sports Car Shop - Eugene OR), it
was determined that the O2 sensor was indeed at "full minimum", and when
replaced, the car ran absolutely perfectly.  At least I have peace of mind
that all other systems checks were performed too.  Thanks to all of those
that responded to my queries!!!  Your help really did narrow down the list
of possible faults! 

Thanks again to all!!!
