Truck will sit and idle fine but as soon as I give it gas it stumbles. After stumbling it'll pick back. It was doing fine I had been driving it and this came out of no where. Ive changed fuel filter,the fuel pump is working,Ive changed plugs, plug wires, distributer cap, and rotor button.

Check the timing. Change the air filter.
