2007 Toyota Tacoma Fuel System Other Problems

I WAS EXITING THE PARKING LOT OF HOME DEPOT IN BARBOURSVILLE, WV IN MY 2007 TOYOTA TACOMA 4X4 AND WHEN I ATTEMPTED TO STOP FOR A VEHICLE TO ENTER THE PARKING LOT, THE ENGINE REVVED UP CAUSING ME TO STRIKE THE INCOMING VEHICLE IN THE PASSENGER SIDE DOOR. DURING THE TIME BEFORE I COULD PUT THE VEHICLE IN NEUTRAL AND TURN OF THE ENGINE, I WAS APPLYING AS MUCH PRESSURE ON THE BRAKE PEDAL AS I COULD AND THE TACOMA WAS STILL MOVING INTO THE OTHER VEHICLE WITH THE ENGINE REVVING AT A HIGH RATE. THIS IS THE ONLY TIME THIS HAS HAPPENED IN THE VEHICLE SINCE I BOUGHT IT NEW IN MARCH 2007. THE TACOMA HAS BEEN CHECKED BY THE DEALER WHERE I PURCHASED IT AND BY TOYOTA'S FIELD TECHNICIAN AND ACCORDING TO TOYOTA NOTHING WAS FOUND. I HAVE BEEN DENIED ACCESS TO THE FIELD TECHNICIAN'S REPORT TWICE. THE ONLY THING THAT WAS BROUGHT UP AFTER BOTH REVIEWS WAS FLOOR MATS. I CAN PERSONALLY ATTEST THAT THE FLOOR MATS HAD NOTHING TO DO WITH THE PROBLEM IN MY VEHICLE. THE ACCELERATOR PEDAL WAS COMPLETELY UNTOUCHED BY ANYTHING AND THE ENGINE WAS STILL REVVING AT A HIGH RATE. THE PROBLEM APPEARS TO BE IN THEIR ELECTRICAL SYSTEM AND TOYOTA REFUSES TO ACKNOWLEDGE IT. *TR
