I know jack squat about the engine and idle control system, but when I was
having this problem with my 88 non-syncro it turned out that the
accelerator line needed to be replaced.  I noticed the pedal didn't fully
spring back after being depressed.  It wasn't much, but enough to make the
engine "idle" around 1500-2000 RPM.  Prior to replacing it, I found I
could pull on the accelerator pedal to slow down the idle to normal
tolerances.

Good Luck!
