truck ideling high

Hello everyone I have a 1991 dodge w250 intercooled cummins, and I Turned my fuel screw way in then backed it out a 1/2 turn, and backed out my idle screw all the way, but my truck still idles really high, what can I do to fix the problem. The truck runs awsome, has lots of power now, but just idles really high. Thanks :argh:

you have to loosen the throttle rod it will also act as a idle screw!!

Check to see if your full fuel screw is backing in and out.My truck did the same thing. If it is i just took a hammer and a big chizzel and bent it a liitle down.
