So after driving the Mustang today I realized that I needed to go about 90mph to keep pace with the left lane. Now, I drove this road all the time and the flow of traffic was never ever 90mph. 85 tops, and that's rare. So I think... hmm maybe the speedometer is reading too high?
So I get my dad to take his car and do a cruise at 50mph and then at 80mph. At 50mph, the speedometer seems to be fine, but when he's doing 80 I need to go like 87-90 to keep pace. So apparently it only reads high at certain speeds?
Any of you guys have this problem before? Any way for me to fix this without taking it to the dealer. I dont mind taking it to the dealer as it's under warranty but I'd rather be able to do it myself. Also, do you think that the speedometer reading wrong also means that my odometer/mileage calculator etc is reading off as well?
I'm running a completey stock auto 06 GT btw.
