indian, There are many things that can cause high idle on your trucks engine, dirty/sticking throttle body, cable/linkage, IAC idle air control motor, EGR valve faulty, vacuum lines/TB base gasket cracked/loose leaking, bad coolant temp sensor,etc. You should probably have a good technician have a look, check for trouble codes, diagnose and estimate repair. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.

I don't know if this will help but its a try :
The air/fuel mixture is controlled by the computer, (ECM) there is a little screw behind the cap on the throttle body that will allow turning the idle up or down. The little cap in toward the front and the screw touches the tab on the throttle lever.
My dad has a 1996 chevy and he wanted his idle at 900rpm to prevent a stalling problem.
