I took my truck into the shop yesterday because it kept stalling when i was driving down the road. Well the dealer just called he informed me that my throttle body needs replaced because the "butterfly" is sticking and cannot be repaired. My question is has anyone eles had to replace this, or is their a rebuild kit, and if i do have to replace it where would the best place to buy one either aftermarket or stock. Thanks for the help guys
