I replaced the idle control motor on my truck; now the truck is idleing too high. How do I adjust the idle?

1990 is going back a ways. If I remember, there is a curb idle screw where the linkage attaches to the throttle. Check that. Also, I need to know if this is the 3.9 V6 and if it is a full size or dakota.

It's a 3.9 V6. It's a full size.

Check to see if there is a curb idle screw. Let me know. As far as the IAC, it isn't adjustable.
