Before you waste a lot of time and money at the dealership fill the tank with top tier 91-93 octane gasoline add two bottles of BG44K, Drive the Raptor fairly aggressive for the entire tank of fuel, get out on the highway where you can do some hard pulls to 90-100+, This will clean the fuel system and injectors while burning built up carbon on the valves and in the combustion chambers. Make sure the engine and transmission are at operating temperature before doing any hard driving. See if that doesn't smooth things out a bit.
