Accelerator Stuck problems of the 2001 Mercury Marquis

We were lucky. The accelerator not only stuck, but snapped down against the floor board. Luckily, I was driving, not my 70+ year old mother, and we were on an open road with no people or objects in front of us. Even so, we were doing appox. 80 mph before I put it in neutral and shut off the key. The dealership did a good job. They discovered that the "wiring harness at lighting control module had somehow gotten into the accelerator mechanism causing the gas pedal to stick down. Though they fixed ours, it bothers me to think of all the terrible things that could have happened had the sitution been slightly different. I file this report in the hope of preventing that "terrible" accident from happening to anyone else. Other than this, its has been a great car.
