New JR Syn Pro Radio Issue????
I just put a new radio system in my truck and it is cool as crap. The New JR PRO Syns. system, BUT, When the truck is running the throttle does not stay open even if I am holding it wide open. It pulsates and partially closes on its own. When the truck is off it functions just great. Is it possible to have some type of interference from the engine running? What in the world do I have going on? Thanks for any help!!!
