ON FEBRUARY 16, 2004 AT APPROXIMATELY 2:30 PM I WAS PULLING MY WIFE'S 1997 FORD EXPLORER SPORT INTO A DIAGONAL PARKING STALL. I HAD ALMOST COME TO A COMPLETE STOP WHEN THE ENGINE BEGAN TO ROAR AND THE CAR BEGAN TO ACCELERATE AGAINST MY BRAKING. I PRESSED AS HARD AS I COULD ON THE BRAKE PEDAL BUT THE CAR CONTINUED TO MOVE FORWARD UNTIL IT STRUCK A CAR OPPOSITE MY PARKING STALL. I PUSHED THE GEAR SHIFT INTO NEUTRAL AND TURNED OFF THE ENGINE. I CHECKED MY RIGHT FOOT POSITION AND CONFIRMED THAT I WAS ONLY PRESSING ON THE BRAKE PEDAL. WHEN I RELEASED THE BRAKE PEDAL THE CAR ROLLED BACK A COUPLE OF FEET. I SHIFTED THE CAR INTO PARK AND RESTARTED THE ENGINE AND BACKED THE CAR UP ANOTHER 3 FEET. THE SUDDEN ACCELERATION HAS NOT RECURRED BUT I AM CONCERNED THAT IT MIGHT AGAIN. *JB
