Gauge sweep every time you start the car
On my 2000 Focus, my daughter's car, I notice that the gauges sweep all the way to max and then down every time I start the car.
I drove this car for about six months when first purchased and don't recall it doing that then in 2011.
The tripometer doesn't reset and the aftermarket radio doesn't loose any info either. No other abnormalities that I can think of except a recurring P0171 that I can't get rid of for more than a year now.
