Does the 3.0 have the Idle air control valve? My chiltons says yes, the dealer says no...? Who's wrong?

The 3vze has a coolant controlled Idle passage. The hotter the coolant the smaller the passage becomes. Fast idle when cold. It's part of the throttle body. There are two 3/8ish hoses that connect to the throttle body. There isn't a electrical IAC like a Honda or Mustang etc... If your truck is revving up kinda high then going back down, then back up etc.. Your probably to low on coolant and the throttle body isn't getting enough coolant.
