80 bucks in labor for an idle air control valve!?!?! It's a 3 minute job to replace that piece. They ripped you off big.
ranger_1999: does it only happen when the truck is moving and is less than 40 or does it happen at idle as well. Try to narrow down where the sound is coming from, that would be pretty helpful.
