My odometer works when it wants and however slow/fast it wants would this be a cluster problem or a VSS problem? Also i know the speedo is off but it varies at 30 mph im really goin 25 mph and 60 mph im doin 59 mph ive checked by gps and those speed trap things the police put on the side of the road

2.3/5 spd 2wd
