    Hello, I have replaced the carb. fuel filter, fuel pump, distributer cap, rotor, plugs wires, new plugs, new fuel tank the truck runs great starts
    on high idle when cold, warms up idles down when I kick It down, theirs no miss the trans shifts great until it shifts into third and I accelerate hard it falls on it’s face like all the fuel is shut off when I let up it’s like it catches up and runs fine until I accelerate it again the same thing. I have checked the choke to make sure it’s operating correctly when I accelerate (I tied it back with a wire tie) help would be greatly appreciated, Thanks

    When you accelerate in 3rd gear does the transmission kick down as it should.

    It starts and runs fine till it’s full throttle or kicks down.

    Have you checked the EGR system for operation or possible clog?

    You can google operation of the EGR valve and methods of testing.
    Also check youtube for any videos concerning operation, testing and service
