Speedo Off, but Odometer is accurate?
Hi all, picked up a 2003 GT a few weeks ago, and the speedo is off by around 6-7 MPH. I have checked it against two different GPSs. I was thinking I could get a programmer and fix it, but I checked the odometer, and it is dead on. Also, I ran the diagnostic tool on the dash, and the digital speedo is dead on. It is just the needle on the gauge that is off. Anybody know what might be causing this or how to fix it?
