hi everyone, new to this site, i have a 2009 chevy silverado 1500 5.3l v8 auto, starts fine, idle fine in park, problem is when driving rpms will spike
set cruise at 60mph, everything fine for about 6 miles then rpms just shot up over 3000, took it out of cruise but still had issue, got it back home
having to go approx. 45mph, every time i gave it gas rpms would go wild, no codes or check engine light appears, took it for another ride to see
if it would repeat issue and now just accelerating causes rpms to surge, would like any input on what the issue could be
