Almost killed myself, thanks Chrysler!!!!!

[Gkomp]

Listen to this. I was on the highway with my 93 concorde when I had to slam on the brakes when the car in front of me slammed on his brakes. I had the cruise control on at the time. When I hit the brakes the car FLOORED the accelerator. I guess the cruise did not shut off. I had to turn into the grassy median to avoid the car in front of me, slip into the opposite lanes of traffic, came 1 inch of hitting a semi head on at 70mph did a few spins and stopped accross the highway in the grass. Nobody hurt, no damage, but infuriated that this happened. I shut the cruise off manually on the steering wheel while sliding in the grass. Has this happened to anyone else? I would personally like to thank chrysler for enginnering such a fine piece of machinery which almost ended my life. Anybody wany to buy a concorde?

WOW, AND ON A CAR ONLY 12 YEARS OLD!

Hmmm, never had the cruise control floor the pedal on ANY car I ever had, even when set to a very high speed and hitting "Accel" from the minimum speed. I'd take it back out and try that again (Without the traffic of course) and see if it can be recreated, If it does then you have a brake light switch problem because according to the diagrams I have, as soon as the switch is depressed it cuts the juice to the Cruise Servo and also cuts the ground connection to the Stop Lamp Switch Sense terminal on the PCM which in turn should dump the vacuum at the servo.

yeah i have a 96 honda and cruise shuts off at a tap of the brake pedal.

Well, here is another thought. Chrysler cars have long had an issue with the throttle cables sticking. When this happens, with or without the cruise on, the engine will not idle back. Using the brakes is useless. If you shift into neutral the engine speed will redline. The only thing you can do is to shut off ign switch. (If you are not panicing as I was a few months ago when this happened to me on another chrysler product, not my concorde). This is most apt to occur after the car has been sitting for lengthy periods of time and not driven. I most often see it whenever, a person has cleaned his engine, washing off all lubrication, and the cable tends to stick at the throttle body. If you work the throttle link a few times it will usually be okay until you let it sit and it again corrodes a little. Also, you should spray some lubrication on linkage points leading into the throttle body. A clean engine is nice, but you have to be careful because you are usually also washing off all the grease such as in bearing pullies (belt adjust idler pullies), the grease in wire connectors which protect them from corrosion, and sometime the lubrication in the water pump. When you gunk or use engine cleaner you also are washing oil all over your belts which are likely to result in the belt squeeling after a couple of weeks. The oil from the engine will glaze the sides of the belt and the only permanent cure for a squeeling belt is to put a new belt on. Belt dressing will only work for a very short time. If you overtighten belt to stop squeel you are likely to pull the bearings out of a component such as the water pump, or alternator.
Anyway in all seriousness, I'm thinking that you might have had a sticking throttle cable. Once throttle is opened it just sticks open.
