Replace your seals, then see if the pressure stays up(no oil light
flicker).  With that many miles, you might be due for a rebuild.  That
still shouldn't affect idle, though.  Have you done a compression
check?

Yes,yes,yes, that sensor is EXTREMELY sensitive to leaks, this will
give you bad idle as will any air leak anywhere in the induction
system.  REPLACE IT NOW!!!!!  From one who knows the hard way.  Check
the seals on the injector ends, too.  One thing I had happen on the
'71 is that the auxilary air valve(sits in what would be the fuel pump
hole on a carbed engine) had stripped the adjustment lock screw and
the valve was swinging back and forth, eventually jamming open.  Drove
me nuts because the idle wouldn't stay set.  Don't have Bentley handy
so I don't know if yours has the electric heater or not, might be
worth checking out, though.
