my '98 was stolen and recovered. When I got the car back, the gague cluster was stolen. I've since replaced it but the mileage on there is obviously off. I've often heard that ODBII vehicals keep track of the mileage internally in the ECM. Is this true? Is there a way to extract this info? My Odo is showing about 50,000-55,000 miles less than what it really is supposed to be.

thanks,
