1998 Mustang V6 Low on power

The only error code it throws is 1507, which means "Idle Air Control IAC Under Speed Error", but the IAC checks 10.1 ohms, and 12+ volts, which s good. It also threw an error code of 8000, but I can't find that code anywhere. I think it is an error of my cheapo scan reader.
In neutral, car revs up very slowly. On a slight downhill, it will get up to 35 mph, after a long time.
Dropped cats at headers, still ran very very weak.
Also, headers glow very red hot, almost white hot.
It acts as if ignition timing is very retarded, but of course there is no way to set the timing.

there is only one reason that i know of to make exhaust manifolds turn red the timing on engine is to far advanced
have the engine timed .if the distributer is loose this will cause it
if distributer is not loose, maybe the automatioc advance and retard on distribuor are not working. this is sometimes caused by clogged vaccuum line going to the distributor
