engine racing at idle?

[98ranger4x4]

my 98 3.0 (5 spd) will rev up at idle when the truck is moving since it has gotten hot (i live in vegas its 100*+) when the truck is moving the rpms will race up to around 3k until i come to a stop and then they drop back down to normal. it did this last summer too and it seems to only do it intermittently, it stopped for a week or so then started again. does anyone have any ideas what could be causing it or how to fix it? thanks in advance!

search for "idle air control solenoid" or the like...its pretty common on ford vehicles. remove, clean and lube, re-install.
