Mike here from El Paso. New to me 1993 C3500 DRW, 2WD, 6.5L, FASS and NV5400.
The fast idle solenoid has been removed as it is very much broken.
Truck idles high 2K-ish or better. Runs good otherwise.

Anybody have any ideas on how to fix this? Any adjustments I can make?

Thanks in advance

I dont havva clue why Your truck should idle so fast, just telling You welcome to the forum.
Those that knows about such matters should be bumping in and replying.

Yep, turn the idle screw out till you get the idle speed you want... Look down at the linkage and you can't miss it...

Welcome @txroadkill nice looking rig. looks like the screw end on the idle solenoid is badly bent. mine was bent but not as bad. if your very careful you can try to slowly straighten it out to the point where it will slide in and out freely. then reinstall on the IP, send 12v power to it and adjust where you want it. this solenoid is for the cold start warm ups. on my truck I tied into it with a one way diode and ran it to a relay that controls an aux cooling fan for my ac. this way when I have the ac turned on the idle is up a touch. it helps when sitting at a traffic stop in this blazing Texas heat!

BTW it's nice to see another fellow Texan here in the forums
