2014 Silverado, 3.42 gears, 5.3L, 75K miles Truck has all the current maintenance. Even recently had throttle body cleaned and relearned, MAF replaced, air filter new, and fuel induction treatment Notice after hard drive pulling or spirited drive on the freeway, when I exit the highway on off ramp, say sitting at a red light, when I take off the truck makes it thru first gear smooth, but literally falls flat in 2nd or 3rd. Feels like a misfire, or lack of fuel, or something. odd thing is, power thru it, next stop light, no issues, drives fine. Dealer cannot replicate, no one has any ideas. Been to 3 dealers and they are all stumped. Any ideas guys? Thank you PS: I know the trucks can be laggy with the Torque and fuel management system, but this behavior is new within the last 15K
