Help my truck wont idle!!!

[Jornum1]

Hey guys I have a 99 sport, my mods are below. It started off that it wouldnt idle sometimes when I started it up, especially on warmer days. I would drive it for 5 or 10 minutes having to feather the gas when I stoped, and then it would be ok. Now it wont idle at all!! Anybody had this problem? Know where to check. Could my idle air control be shot? Any way to check.
THanks

Sounds like the IAC to me. So many people have said the same thing about the 99 model year trucks.
