Mathew,

Check the adjustment of your throttle position switch.  If your engine is an
early '85 you may have two switches -- one for idle position and the second
for full throttle.  If you have a later model there is a combined switch
below the throttle body.  In either case you may need to adjust the idle
position function.  You'll need an allen wrench, multi-meter, a feeler guage
and three hands but it is a fairly straight forward process.

When I replaced the combined switch in my '85 I found that just getting the
switch to function consistently is more important to smooth running than
keeping the adjustment perfect according to the Bentley Gospel.
