Has anyone else seen their MPG meter indication constantly jumping up and down? Mine was doing it yesterday at a rate of about 2 to 3 times per second with a magnitude of, perhaps, 2 to 4 MPG. Not at all the normal reading that just changes smoothly with road and speed. No water on the road, temps about 70F, didn't matter if HVB was being charged or supplying power. Tach and speed were steady. Car seemed to be running normally with gas mileage unaffected. Saw it for over an hour - AFAIK, till the end of the trip.
