Z69

I remember a post that discussed this a while back. But I read so many I loose track of the more obscure stuff.
Was only a few things that caused it.

It's a 91 Caprice.

Rest of the story:

Guy I know has this problem.
SES Light comes in every once in a while, but no codes stored.

Car has 300K on it.
Car ocassionally falls on it's face while driving. Sometimes can't give it hardly any throttle at all. Wouldn't start once.
Changed the following.
Coil, cap, rotor, wires, plugs,oil,MAP.
Checked ign. module, FP is 12psi.

Thoughts?

The TBI forum was almost useless...

Too many miles = junk
Suddenly "my" 300k 383 has wiring issues?
Replace something already replaced...
