I am having issues with my throttle body and specifically I believe the throttle control module. I was backing into a stall when randomly I received the reduced engine power display and I lost all throttle response and the idle became rough. I did all the things I thought to get it going, resetting sensors, wiggling the grounds, and ensuring all plugs are connected. And it still wouldn't run right. And I believe my issue is with TAC or throttle actuator control module as when I start my truck it will run fine with no issue but the second I hit the gas the message returns and the zero response and rough idle comes back. I am going to the junkyard to grab a new one to ensure that is the issue as rockauto won't get to my house till later this week and the local shop wants $550 for the part alone. So I will get the part and see if it works and if it does Imma get the one from rockauto. However, I want to see if anyone else has any other ideas. The codes coming up are the following: p1516 p2108 u0107Thank you all!Jayden</blockquote>
