What's Up Forum? Having A Bit Of An Issue With My 2003 6.0 Yukon Denali. I Kept Getting A Code For The Throttle Body Actuator And Finally Replaced It. I Hit My Automatic Start Last Night And After About 10 Minutes I Went Out To Get Into The Truck. After Unlocking The Doors With The Alarm Pager, I Noticed The Truck Idling Differently. As Soon As I Opened The Door I Saw The REDUCED ENGINE POWER Message On My Dash. I JUST Replaced The Throttle Body Because Of This. Reading Some Stuff On YOUTUBE They Say It Can Also Be The Ground Wire. Anybody Have Any Experience With This That Can Help With Trouble Shooting? It's Frustrating At This Point. Any And All Help Is Greatly Appreciated, Thank You
