PURCHASED 05 NEON IN '06 W/16,000 MILES. TIRES WERE ALREADY IN BAD SHAPE. CURRENT INCIDENT OCCURRED WHILE ACCELERATED ON ENTRY RAMP TO FREEWAY. ONCE ON FREEWAY NOTICE VEHICLE WAS ACCELERATING ON ITS OWN. ATTEMPTED TO APPLY BRAKES AND THEY WOULD NOT ENGAGE. I ASSUMED BRAKES HAD FAILED. FINALLY AFTER A TERRIFIED EXIT FROM THE FREEWAY, I WAS FINALLY ABLE TO COME TO A STOP MY EVENTUALLY ENTERING A VACANT GRAVELED, UNEVEN LOT AND DRIVING ATOP CONCRETE BLOCKS. MY TERRIFIED PASSENGER AND I PUT IN PARK, TURNED OFF THE IGNITION AND JUMPED OUT OF THE CAR. WHEN AAA ARRIVED, HE SAID MY GAS PEDAL HAD STUCK. THE CAR WAS TOWED TO MY HOME. WHEN A MECHANIC FRIEND CHECKED IT OUT HE FOUND THE AIR THROTTLE CONTROL VALUE WAS SHOT. WITHOUT THAT, THE ENGINE WILL NOT IDLE PROPERLY. I AM STILL IN THE PROCESS OF GETTING THIS FIXED. THE PART HAD TO BE ORDERED. I AM NOT SURE IF THAT IS THE ONLY PROBLEM. THERE WAS NO PROPERTY DAMAGE. MY FRONT DRIVER'S SIDE TIRE AND RIM WERE DESTROYED. *TR
