That symptom is almost completely diagnostic of a bad or misadjusted idle
switch (on the throttle body).  Switch should close at closed throttle and
full throttle (if there are two switches, one closes at idle and the other
at full, but they're connected to the same wires so the effect is like one
switch.

Test/adjustment is in Bentley (don't have it handy).  Also in Haynes, but
only for the single-switch models ('85-up)

Quick check is pull the wires off the switch and bridge them -- idle should
be smooth.
