Car Throttle Stuck problems of the 2003 Honda Accord

I was on an old six-lane highway where the speeds were 45-50 mph. My car suddenly fully accelerated, just as if I had floored the accelerator. I was unable to brake it to a full stop without hitting the car ahead of me or going through a red light and fortunately I was able to drive it part way onto a median strip and throw it into park and then shut off the engine. No one was injured and there was no damage to the car. A passing taxi driver checked the engine and said the throttle was stuck fully open. He was able to fix the throttle and drove the car off the highway, where I waited for a tow truck. My mechanic ran computer diagnostics on the car but could find no problem. He was also unable to reproduce the problem until one of his staff experienced it while backing up the car. The only thing he could propose was to replace the throttle body, which did not appear to need replacing. My researches led me to believe that this is a computer failure. I no longer own the car.

The contact owns a 2003 Honda Accord. The contact started the ignition and as the accelerator pedal was depressed, the vehicle unexpectedly increased acceleration to 70 mph. The brake was engaged repeatedly and the gear was shifted into neutral however, the vehicle continued to accelerate. The speed was reduced as the vehicle accelerated up an incline then the contact shifted into park. The engine began to roar loudly with a rapid increase in engine rpms. The engine was turned off and the vehicle came to a complete stop. A certified mechanic arrived on the scene to inspect the vehicle. The mechanic found that the accelerator pedal had become stop in open throttle position. The vehicle was able to resume as normal. The manufacturer was notified of the acceleration failure and the vehicle was taken to an authorized dealer for diagnosis. The dealer however was unable to duplicate the problem. In addition, an investigator inspected the vehicle and detected that the air filter plastic box was fractured, which caused fragments to remain stuck in the throttle. They also informed the contact that the air filter was improperly installed by a mechanic when performing a previous oil change. The approximate failure mileage was unavailable.

The contact owns a 2003 Honda Accord. The contact stated that while driving approximately 65 mph the vehicle seemed to accelerate when she attempted to pass another vehicle. When the brakes were applied, they failed to stop or slow the vehicle down. She was able to maneuver into the right lane and engage the parking brake. She was able to drive slow enough to turn the engine off and park the vehicle. She towed the vehicle to the dealer where she was informed that valves in the throttle body were stuck which caused the failure. The vehicle was being repaired when complaint was filed. She called the manufacturer but they offered no assistance. The current and failure mileages were approximately 116,000.
