My L3901HST is blowing the 5 amp fuse from the ignition to the Main ECU when I let up on the speed control pedal. Makes me think its the acceleration sensor, but why would it blow when I let up on the pedal instead of pressing down? Do you think it is the sensor or the ECU? This started when I started getting an E 20 code. I think I have that fixed since it isn't showing up anymore when I turn the key.
