2009 Ford Mustang UNKNOWN OR OTHER

PULLED UP A DRIVEWAY AND PUT MY 2009 FORD MUSTANG IN PARK, STARTED ACCELERATING ON IT'S OWN. WOULD DECELERATE AFTER PRESSING AND RELEASING THE GAS PEDAL BUT WOULD START ACCELERATING AGAIN ON IT'S OWN. TURNED THE CAR OFF AND WHEN RESTARTED ACTED AND DROVE FINE. HAVE READ THAT THIS IS A COMMON PROBLEM THAT HAS NOT BEEN ADDRESSED BY FORD. VERY UNSAFE PROBLEM.

THE HOOD IS SEVERELY RUSTING ON THE FRONT EDGES

I WAS APPROACHING A STOP LIGHT WITH 3 VEHICLES AHEAD OF ME. I HAD SLOWED DOWN ALMOST TO A COMPLETE STOP WHEN ALL OF A SUDDEN THE ENGINE ROARED AND THE CAR LURCHED FORWARD INTO THE BACK OF THE PICKUP IN FRONT OF ME. I HAD THE BRAKE COMPLETELY TO THE FLOOR AND THEN MY REAR WHEELS BEGIN SPINNING WITH THE MOTOR STILL ROARING. I WAS FINALLY ABLE TO PUT THE (AUTOMATIC TRANSMISSION) CAR IN PARK AS IT SEEMED TO BE STUCK WHEN I FIRST TRIED TO GET IT OUT OF GEAR AND STILL THE MOTOR WAS REVVING UP AND STILL LURCHING FORWARD AND TURNED THE KEY OFF AND IT SHUT DOWN. MY FRONT BUMPER WAS DAMAGED IN THE ACCIDENT. NO WARNING LIGHTS WERE SHOWING ON THE INSTRUMENT PANEL. MECHANIC STATED NOTHING PICKED UP DIAGNOSTICALLY IN ORDER TO PINPOINT THE PROBLEM ALTHOUGH THE ASSUMPTION WAS IT WAS EITHER THE TPS OR POSSIBLY A VACUUM LEAK. I HAVE THOROUGHLY ENJOYED THIS CAR AND PRIOR TO THIS HAVE NOT HAD ANY PROBLEMS WITH IT, BUT NOW I AM AFRAID TO DRIVE IT.
