My van practically jumped into motion when I turned it on. It will roll in motion without my foot on the pedal and the pedal feels like it is sticking as if I am riding on cruise control. It idled a little high when placed in park. What could be the issue?

Some other possible causes: Factory - drivers floor mat installed correctly and no aftermarket mat or overlay? Foreign object in drivers floor pan? Positive you didn't push the accel. pedal? Does it do this every time? If it is a mechanical problem or a vacuum leak it should happen quite often! Check engine light on?
