I went through a whole bunch of stuff to try to eliminate a similar problem
with my '85.  Start with the cheap stuff first.

Make sure the intake boot is well attached and in good condition.  (This was
actually my final solution after all the other stuff.)
Check the carbon track in the AFM -- mine had a bad spot just above the
normal idle position.  I enlarged the screw holes in the board and shifted it
so that the arm ran on a fresh track. (This was my next to the last step and
solved most of the problem.)
Check on the condition of all the vacuum lines -- especially those small ones
attached to the fuel pressure regulator.
Check the fuel pressure and function of the fuel pressure regulator.
Try tightening the AFM spring some.  Be sure to keep track of the number of
notches you move the wheel -- you may want to put it back at some point.
