Hello my name is Dan I have a 2013 silverado 5.3 I have a ticking noise and ruff idle/misfire. When give engine gas I have hesitation. If I reset computer it goes away but returns after a short time later. A couple times when speeding up the throttle stuck wide open until I tapped the peddle again. Jot sure were the issue is here any one ever heard of this problem
