I have 98 Pathfinder, this recently started happening. Turn the key on, instrument panel freaks out. Temp gauge maxes out, gas gauge maxs out. RPM bounces, speedometer has bad reading (usually stays at or around 10-15 MPH) The odometer says 9999999. I will drive the car for a period of time and at times it is ok, other times has same issue. Any thoughts would be appreciated.
