Speedo not reading right and odometer not working
i have an 89 firebird. all the other gauges work. the speedo reads about 3mph off when your going under 30mph but the faster i go the further off it gets. and the odometer dosnt work at all. i really need some help on this one. i cant seem to figure out why the odometer isnt working. anyone have an idea.

most of the time speedo is off cause of either rear end change or a gear swap

An 89 Bird should have an electronic speedo.
