I installed some lighted gauge faces the other day and I went to drive the car today and my speedometer is wayyy off now. It doesn't move at all until about 25-30 mph and seems about 20 mph off on the slow side at highway speeds. The odometer and trip odometer still seem to be working right. I checked the needle and it isn't catching on the new gauge face, so that's not causing it. The tach is fine though. Any ideas?
