I DRIVE A FORD "PROGRAM CAR" - A USED 2007 CROWN VICTORIA (A FORMER RENTAL VEHICLE). ON THE DAY OF MY ACCIDENT - AFTER PULLING ONTO A BUSY STREET FROM A PARKING LOT - I ALMOST IMMEDIATELY APPLIED MY BRAKES BECAUSE I WAS COMING UP TO A RED LIGHT WHERE SEVERAL CARS HAD ALREADY COME TO A STOP AHEAD OF ME. AT FIRST MY CAR SLOWED NORMALLY BUT, AS I APPLIED THE BRAKES TO COME TO A COMPLETE STOP, THE ENGINE BEGAN TO REV' UP. I TRIED TAPPING THE BRAKE TO SEE IF THIS WOULD HELP TO DISENGAGE THE THROTTLE'S REVVING. IT DIDN'T HELP. I KEPT TRYING THIS. I HAD LITTLE TIME TO COME TO A STOP BEFORE HITTING THE CAR IN FRONT OF ME SO I REALLY "STOOD" ON THE BRAKES. UNFORTUNATELY, I HIT THE BACK BUMPER OF THE CAR IN FRONT OF ME. LUCKILY, THERE WAS NO VISIBLE DAMAGE TO EITHER CAR AND NO ONE WAS HURT. THIS SAME SITUATION HAPPENED TO ME ABOUT 2-3 WEEKS BEFORE THIS ACCIDENT OCCURRED BUT THAT OCCURRENCE DIDN'T RESULT IN AN ACCIDENT. I WAS ABLE TO TAP THE BRAKE PEDAL AND THE REVVING SEEMED TO INSTANTLY GO AWAY. I HAD A PASSENGER WITH ME AT THE TIME. I HAD THE SAME THING HAPPEN WITH ANOTHER SIMILAR CAR IN THE PAST - A MERCURY GRAND MARQUIS. IT HAPPENED MORE THAN ONCE AND NO MATTER HOW OFTEN I WENT TO THE DEALERSHIP TO GET HELP THEY KEPT TELLING ME THEY COULD NOT "REPLICATE" THE COMPLAINT. I TOOK MY CURRENT CROWN VICTORIA TO THE DEALERSHIP ONE DAY AFTER HAVING THIS MINOR ACCIDENT. THE CAR WAS DUE FOR A SERVICE VISIT AND I TOLD THEM ABOUT THE MINOR ACCIDENT AND ASKED THEM TO SEE WHAT THEY COULD FIND OUT
