Hi my name is***** will be glad to help. Yur problem can be a few things... Harness, Throttle control dial(test with a volt OHM meter for increasing and decreasing voltage when moving the dial or if disconnected test the resistance when moving the dial and check for any loss of signal), Controller, or stepper motor/actuator. Most likely it will be either the dial or the stepper motor. I would check the harness and test the dial first and let me know the results and if we need to dig deeper into this.
