I WAS COMING INTO DEWITT ARKANSAS ON HIGHWAY165 ON 12/13/09 AT ABOUT 12:30PM WITH MY CRUISE CONTROL ON AT ABOUT 60 MPH. I TAPPED THE BRAKE TO DISENGAGE THE CRUISE CONTROL AND SLOWED DOWN TO MAKE A RIGHT HAND TURN INTO AN EXXON MINI MART. MY 2006 TOYOTA 4RUNNER SUDDENLY ACCELERATED AS I ATTEMPTED TO STOP NEAR THE FRONT DOOR. AS I APPLIED PRESSURE TO THE BRAKES I HEARD THE ANTI LOCK BRAKES CLICKING AND SUDDENLY THE 4RUNNER LUNGED FORWARD STRIKING A LARGE POLE THAT WAS IN FRONT OF ME. THE REAR WHEELS WERE SPINNING WILDLY AND THE BACK END WAS BOUNCING UP AND DOWN. THE 4RUNNER WAS BOUNCING TO THE SIDE AND I SLAMMED THE SHIFT LEVER INTO PARK. THE POWER TO THE BACK WHEELS STOPPED. I SAT BACK AND TOOK MY FOOT OFF THE BRAKE PEDAL, THEN I NOTICED THAT THE ENGINE WAS STILL RUNNING WIDE OPEN THROTTLE. I REACHED UP AND TURNED THE KEY OFF. I LOOKED AT THE FLOOR MAT AND IT WAS IN ITS NORMAL LOCATION WITH NO CONTACT WITH THE GAS PEDAL. THE TWO HOOKS WERE ATTACHED HOLDING THE FLOOR MAT IN PLACE. THERE WAS NO WAY IT COULD HAVE BEEN INVOLVED. TWO EMPLOYEES CAME OUT AND ASKED IF I WAS OKAY. I TOLD THEM I WAS OKAY, BUT SCARED TO DEATH. I TOLD THEM I HAD HEARD ABOUT TOYOTAS HAVING A SUDDEN ACCELERATION PROBLEM, BUT I NEVER THOUGHT I WOULD BE INVOLVED IN ONE. I HAD TO WALK AROUND A WHILE TO CALM DOWN. I GOT THE EMPLOYEES NAMES AND PHONE NUMBERS IN CASE I NEEDED THEM. I WENT BACK OUTSIDE AND STARTED THE 4RUNNER UP AGAIN AND IT RAN NORMAL. I DROVE IT TO MY DAD'S AND LEFT IT THERE.
