2003 Taurus SEL sedan.
While driving without hitting a bump, a click comes from under the dash and the idiot lights come on, the gas guage goes to empty, the fan turns off and the speedometer flutters. After a few minutes it all goes back to normal. I had it at the dealership who spent two hours on it and couldn't find a problem. They errased some computer codes but this didn't help. Any suggestions would be great.
