2012 HARLEY-DAVIDSON Fxdc

WHILE DRIVING THIS MOTORCYCLE, AFTER ABOUT GOING THREE TO FOUR MILES, I RELEASED THE THROTTLE AND THE MOTORCYCLE WOULD ACCELERATE, AND NOT SLOW DOWN. I FORCED THE BIKE TO STOP BY DOWN SHIFTING IT AND PULLED INTO A PARKING LOT AND THE ENGINE WOULD NOT SLOW DOWN WITHOUT TURNING THE IGNITION SWITCH OFF. I STARTED THE BIKE UP A FEW MINUTES LATER , AND HAD TO SHUT IT OFF ON THE WAY BACK HOME MORE THAN ONCE TO KEEP IT FROM ACCELERATING AGAIN, THE ENGINE WOULD IDLE BETWEEN 2400 AND 3100 RPM'S. IT DID THE SAME THING FOR THE NEXT TWO DAYS SO I TOOK IT BACK TO THE DEALER WHERE I BOUGHT THE BIKE. THE DAY I TOOK THE BIKE TO THE DEALER IT WAS HARD TO START AND WOULD NOT KEEP RUNNING. I CALLED HARLEY DAVIDSONS CUSTOMER SERVICE, 800-258-2464 AND TALKED TO JOHN WHO TOLD ME HOW TO RUN A DIAGNOSTIC TEST TO CHECK FOR FAULT (TROUBLE CODES ) AND I RETRIEVED A CODE # PO507 WHICH IS A HIGH ENGINE IDLE, IDLE SPEED CONTROL MOTOR. I FEEL THIS IS A SAFETY HAZARD BECAUSE THE BIKE WILL NOT DECELERATE WHEN THE THROTTLE IS RELEASED. *TR
