This is normal, if you turn off the car and wait about 10 seconds after the main rear view mirror lights turn off you will see the rpm, and mph, go up about half an inch and then go bellow the 0.

With all these electrical gremlins in these cars... you think a grounding wire kit would help out with some of this?
