Speed Control Cable problems of the 2000 Honda Accord

1. The events leading up to the failure: 133k miles on 2000 Honda Accord, 4 door, lx 4cyl, 5 spd manual trans. I'm the original owner, purchased in Nov of 1999. Car has been driven daily 15-30 miles with no problems. Regular maintenance has been performed. The car is in excellent condition. 2. The failure, how often it occurs, it's consequences: on 8/3/10, started to drive to work. After 2 miles, I came to a stop light. When the light turned green, I accelerated. When I went to shift from 1st to 2nd gear, the engine over-revved - up to the rev limiter, even though I had taken my foot off the accelerator in order to shift. I coasted with the clutch depressed while the engine "bounced" off the rev limiter for a second. Then I shut the engine off. I could not "un-stick" the throttle -which was stuck in wot (wide open throttle) position. 3. What was done to correct the failure; I. E, parts repaired or replaced (and if old part is available)? I tried to lift the throttle off the floor, it was stuck. I removed the floor mat, which made no difference. I then opened the hood. I could see the throttle cables were slack and that the throttle body was stuck. The part of the throttle body which holds the cruise control accelerator cable had broken. When I stepped on the accelerator, the cable (no longer held in place) flopped forward and jammed the throttle open. Untangling the jammed throttle body, and securing the cruise control throttle cable to a location where it could not come loose, allowed the throttle body to work again. Used throttle bodies are available - $135 +/-. New throttle bodies are available $400 approx. Labor is 1-2 hours to replace. Very dangerous condition. Easy for me to repeat this. I have not repaired this yet. I called the dealership - they wanted to see it. I took it to my mechanic, he verified that the throttle body broke (failed) in a troubling way.
