The bolt that hold the throttle in place when in idol and control how far the throttle can go back so basically to change where is idols, it fell out i think the peice that restricts it from going unscrewing broke off because it idoled really high for a bit then started bogging and then a check engine lights came on, i knew exactly what it was. so the vibration of my truck must have unscrewed it while wheeling today. Should i get a brand new one or go to the salvage yard? is there an actaul name, i hope you guys know what i am talkng about

 

I have no idea what you just said but...if ya need a replacement tbody, if its a 3.0..I got one. lol

 

I think any screw that will fit will work, just put a nut on it so you can lock it in place when you get it adjusted right.
