Check your TPS (throttle position sensor). Should read .35-.65v with throttle fully closed. At full throttle should read 4.0v +

Once you have it adjusted check the operation of the sensor by watching output voltage while you slowly turn the throttle blade. If it drops to zero at any point, you need a new TPS.
