My speedometer has a mind of it's own, occasionally it will work fine, but most of the time it is clocking twice the speed or pegged at 100 mph. Two weeks ago it started jumping around and the tranny was shifting up and down along with it, I replaced the Vehicle Speed Sensor (no cable...all electric) and it was fine for a week, last week it started pegging out at one hundred as soon as I turned on the ignition. Last night it started working fine again
It's about to drive me crazy! Anyone have similar issues?....any help would be appreciated.
BTW, it's a '91 Ram B350, 360 ci, 4 speed automatic with electronic overdrive
