A month ago I bought a 2001 Ford Taurus at 84,000 MI after having it for a couple weeks I realized that it was still at 84,000 miles so I started monitoring the odometer and seen that the last three digits are moving but the 84 stays at 84 I have my second odometer reset after getting an oil change and it climbed to 7,000 miles yet my original odometer is still at 84,000 for only some of the odometer numbers to change but not the rest thank you so much for your help
