2009 Chevrolet Silverado 1500 stumbles without CEL

2009 chevy Silverado 5.3 flex fuel no codes but engine stumbles while its at a stop sign running any ideas Thanks

Assuming no CEL. If mine, would first try some fuel system cleaners such as SeaFoam.
If that doesn’t help, throttle body needs attention or vacuum leak.
