[W126 Coupe] got a code "5" oxygen sensor needs replacement

[Jonathan Hodgman]

I've been having some difficulty w/ the Mustang sensors as of late, namely
they seem to fall out of spec sooner.  The symptoms I'm seeing are correct
A/F @ idle (and thus good lamda #'s) but @ cruising it is running rich, ie
in the low 13's...but most troubling of all is @ WOT where I'm getting
15-16-1..ie, Very Lean!

I've dropped a fresh genuine O2 into one of my cars and am watching to see
how it holds up.  The last Mustang O2 sensor hung in there for about 10,000
miles.
