Spitting and sputtering

[Kmangas42]

So the truck is spitting and sputtering when I press the gas harder than normal and at higher speeds 50-65 doesn't accelerate much more than that also after running it kinda hard when coming to a stop it starts to bog down like its about to die but doesn't die ....if the MAF is unplugged it runs completely fine except at idle I have no idea what is wrong found a worn gasket between the intake manifold and throttle body replaced it and also replaced the MAF and the fuel filter also used a fuel injector cleaner checked for any vacuum leaks couldn't find any idk what to do running out of ideas
