Smooth at first start then after temp comes up chugs along, won't take increase in accelerator. Changed plugs, wires, front O2 sensor, fuel filter, dist cap and rotor, PCV. Is there and engine control module or rear O2 sensor that could be problem?

Check the fuel pressure and then turn around and test out the throttle position sensor/switch.
