[Guiseppe]

Reset ECU, went through 2 tanks of gas and add engine/ fuel injector cleaner. Truck is still running sluggish at times. Half of the time it feels fine, acceleration is good from a stop and while driving. Seems as though RPMs are higher when accelerating before shifting. Also when driving it almost feels like the brakes are being applied and pulling the truck back but they are not. Any ideas, thanks in advance
