various warning lights blinking? While driving the freeway at 70mph, the gauges stared jumping all over the place. All but the fuel gauge and tac went crazy. All of the other lights started blinking irradically also. The backup display for the gauges were working and showed that everything was fine in the car. Could this be a ground problem somewhere (if so, where would I look) or could it be an ignition switch? The gauges even jump a little when you turn the car off.
