Since im not seeing it in the PC/ED or workshop manual,
-i would either adjust it with the IAC disconnected to about 700 RPM
or
-adjust it with the key on until the TPS voltage is less than 1v, around .96 is optimal. if you havent removed the TPS since you adjusted the screw you should be able to use the second method

everyone says it is the "green" wire, i cant verify this since im in bed, but you back probe one of the wires and conect the other lead to ground, turn the screw to .96v and then at WOT you should be close to 5v. disconnect the battery for about 10 minutes and start it and see how it runs

That is what I read. Unfortunatly there is no green wire. So I will continue researching. Thank-you for all the help you provided. It is appreciated.

I found mine to be mis-adjusted when I purchased the truck causing it to take forever to loose rpm.
I ran the screw out untill it no longer touched the throttle body, and then back in so it just barley lifted it. I found that to work for me just fine. At first I didn't turn it in enough and it was closing all the way and making a seal, causing it to bind for a split second. A half turn in on the screw and it was fixed.
Hope that help for a non tech possibility. lol

I think Stranger has it right. My throttle screw was adjusted too low when I bought my Ranger new. The throttle would slightly stick sometimes at idle. I adjusted the screw in a little and the problem went away. I think that adjustment screw is there to keep the throttle plate from sticking in the throttle body by preventing it from fully closing to a binding position.
