stumbles on acceleration

PICTURE THIS.   89gt.  no codes.  Car idles fine, all temps.  problem occurs at all temps.  Idle speed okay.  

WHEN THE THROTTLE INCREASES BY A SMALL AMOUNT [1/16" OR SO] THE ENGINE SPEED DIVES TO ALMOST STALLING.

All main ign. components check fine.  All main fuel components check fine.  stock intake, stock exhaust

Suspect dirty TPS / IAC valve, but thats why I'm posting.

Its really annoying, b/c the clutch out gas pedal down simultaneous action from a stop would probably cause our bnet drivers to stall the engine.  So I launch higher than normal.  

All else is fine, drivability is fine, this problem just makes it annoying  - EVERYDAY  

22mpg+ I've been getting, so... car seems healthy!

Any ideas?

Andy

Test the TPS and see if it's within normal ranges.
