4K bog at WOT

["McMurray Michael" <McMurray_Michael@macmail1.cig.mot.com>]

All-
A friend of mine's '85 4KCSQ 120k+ miles has a serious bog and power loss
problem at high throttle openings.  We checked the WOT switch at idle. 
Activating the switch causes a loss of rpm.  The switch also ohms out okay. 
He thinks he needs a fuel distributor.  Vacuum hoses and related paraphenalia
look good.  The car has excellent compression, ignition stuff, the works.  The
engine runs fine right up the same spot on the accelerator, every time.  Any
ideas?
TIA
