What would make a speedometer go from 0 to 5 mph when I rev my engine up a little bit while idling in park, and then fall back to 0 when I let off the accelerator? At around the same time this started, I also noticed that sometimes on a cold morning when I start my car, as soon as the car starts, the car acts like it moves forward a half-inch or so even though it is in park. The car seems ok otherwise.
