just bought a '98 GT 4.6, 5spd. the speedometer works but reads way faster then what it should, at 20mph it reads 90mph so on and so forth, the rpm's seem to work fine, but the Odometer and trip meter isn't advancing at all.

this is my first mustang, i am mechanically inclined but would like to get some words from the mustang guys them selves.

thanks in advance.
