I was driving my 2000 dodge ram 1500 4x4 truck on interstate going 70 mph and started to slow down due to exit traffic. when i applied my brakes my truck went into acceleration. no cruise was on. kept applying brakes and truck kept acceleration. kept applying brakes and finally got speed down to 20 mph. i'm in panic mode and not knowing what to do i put the truck in park and then turned the key off. brakes smoked badly. got out of truck to see problem and the throttle was stuck. started truck up again and it did the same thing but this time put gear in neutral and turned key off. unstuck throttle again. i was able to get truck to a mechanic. they checked the throttle kit and it seemed ok (it was not one that was on a recall list). the mechanic didn't really know what caused problem. they put a new kit in and cleaned fuel injectors and it has been running ok. fortunately i was on interstate hwy. if i had been anywhere else i feel certain i would have caused an accident. this caught me by total surprise and not knowing how to handle a vehicle in this situation i feel i was pretty lucky that i didn't burn my brakes up, blow my transmission or get killed. i wish i knew what really caused this problem. *tr
