I've had the same problem in my '99 Contour SE. But I do have another symptom, though I'm not sure it's related. Sometimes when stopped at a light the idle kicks up a notch that if I don't stand on the brake the car will jerk forward and then go back to a regular idle. This sudden burst in power happens about every 5seconds. But I have only noticed it when at a stop in Drive and only occures a few times a month.
Thank's
