2014 Chevy Silverado LT 5.3L crew cab. 
Engine hesitated when accelerating at low

speeds. Feels like truck is skipping or buckling in a sense. Need to press gas down all the way for truck to go anywhere. Also notice I’ve been filling the tank more often and travel the same distance. Plus no engine light on. 
 

Changed plugs and wires early last year. Dealer checked catylatic converter and said it was good. 
 

pls help!!!

That is strange that the misfire code is not setting, how many miles?

have to determine if it is Fuel or Ignition, check fuel pressure, may be a "Bad Gas" issue, is it a Flex Fuel engine?, are you running normal fuel (E10)?. If you have the ability you record a Data Log with a scanner is a start.
