While driving my truck it seems to buck around 2000 rpm's. If I accelerate it quits doing this. In the mornings is when it is at its worse. I have replaced the fuel pump, plugs, wires, cap and rotor.

Remove the crank sensor and look to see if there are contact marks on the tip of the sensor. If there are, replace the sensor and install a shim on the sensor. The shims are available at your local dealership.
