I own a 2003, chevrolet astro. on sunday, june, 28, 2009, i was driving on i-94, between alexandria, mn and fergus falls, mn. i had my cruise control set at 70 mph, the posted speed limit, when i approached a vehicle that was traveling at a slower speed. i pulled over to the left lane and proceeded to pass. as i was passing, i looked in my rear view mirror and noticed a vehicle was coming up to me at a fast pace, so i stepped on the accelerator, to get by the vehicle, that i was passing, a little quicker. when i passed the vehicle, i let up on the accelerator, to get back to the speed i was previously traveling. instead of my vehicle slowing back down, it continued to go faster, i touched my brake pedal, to release the cruise control, but my vehicle continued to pick up speed, 80mph and climbing. i then stepped on my brake, on and off, to get back to about 60mph, moved my switch,for the cruise control, to the off position. i continued to pick up speed. there just happened to be an exit, to a town, so i went up the exit, stepping on and off the brake pedal to slow down. when i got to the top of the exit, i turned off the ignition and with the help of braking, i coasted to a stop. at this point, both my wife and i were very scared. i thought my cruise control had stuck, so i turned on the ignition and the engine roared, so i shut it off. i tried it once more and the same thing happened. then i knew it was more than the cruise control, so i called my roadside service. after about a two hour wait,they brought my van to a chevrolet dealer in alexandria, mn. it wa determined, by a mechanic, the next day, that my accelerator cable was frayed and that caused it to stick. the accelerator cable was replaced. i have the frayed cable. *tr
