01 24v reving
 

Ive got a 2001 24v with the edge juice with attitude and a cts moniter.

When ive just started driving the truck (ECT below 140) sometimes itll idle up 3-500 rpm without me tellin it to. once it gets to 180-190 it'll stop. Not sure what it is mayb the TBS, idk im new to the ISB world. Any help would be appreciated.
