Has anyone had to replace there idle control valve on there v10? I have a 99 f250 v10 and i think it may be going out. At low rpm the truck has a looping engine rev. Does this sound like maybe its the idle control valve? I have a 97 f150 and it was having problems staying idling so i replace it and it solved the problem. Any ideas?

 

I was refering to idle air control valve
