This is the first major safety incident with a stuck and wide-open throttle. I just started from a left hand turned at a stop light. I noticed the 2004 Nissan Frontier pickup truck began to increase its speed without any extra pressure applied to the gas pedal. I applied the brakes to slow down the truck's speed while the engine continued to increase speed. I turned on the flashers to warn traffic. I put the truck into neutral while braking and the engine immediately revved to high and loud rpms. I heard the engine making a shift in its high rpm revving noise, and I turned off the engine. I was now fully stopped near the curb. Next, my husband started the engine after a few minutes of being stopped. The engine immediately started revving to the high rpms. Since the truck was parked, he tapped the gas pedal a few times which seemed to reset the engine's wide-open throttle. Safety issue: the engine revved to very high rpms and speeded up on its own; brakes were not fully stopping the truck. Failed component: the engine's "throttle".
