3 days in a row now I've cranked the truck, flipped the AC on, and within 30 seconds start to feel the idle get rougher and rougher until some loud injector knocks get thrown into the mix. Touching the throttle feels fine but as soon as it's back down, rough idle is back and the sharp injector knock. Turn AC off and everything goes back to normal. If I'm driving down the road and turn the AC on, theres no issue for the remainder of the drive. Seems to only act up when first starting and idling. What in the world could I look for? 2004 HO 6sp.
