Measure the throttle pot. You should be getting a range of 0-5k ohm. 0 being no throttle 5 k being wide open. You can measure the 2 wires by disconnecting them at the controller while pushing on the accelorator pedal and the cart jacked up and placed on jackstands. If you unplug the 2 throttle wires and it still takes off when you puh the pedal you have problems with the main power wiring somewhere.
