Ok - thanks for the replies.  To answer the few questions - I changed the
FPR with a low milage, known to work one; I also spliced in an O2- but
have not had problems with that in the past, plus the wires looked good,
and I checked the output at the terminal on the engine - it seemed to be
reading there - the code basically tells me that there is another problem
with the engine, and that it is so far out of range, that the o2 can't
sense the actual o2 content because it is either too high or too low. 
This leads to the other comment about the coolant sensor behind the pass
side head.  Someone mentioned that it may be bad - I checked it but I
think I will replace it with a known good one just to be sure.  This thing
has me baffled.  One more thing, I know that I have said this but, One
cylinder is low on compression - I know this could cause this problem, but
I don't think it is.  Maby denial?  The car just runs so well otherwise.  
                       Jason
