hey all-
Odd problem. When I am accelerating past 70, the speedometer will rise normally until about 75, at which case it will start twitching and go down. It dosen't drop to 0, it gradually slows down, so that by 78ish, it shows 60, at 80 it shows 40, and by about 85 it's at zero. I *think* the odometer stops turning, but I haven't had much time over 85 to test this idea. I'm reasonably sure cruise control works fine during the fault.
Could it be a bad signal? Bad speedometer? I recently installed a 98+ radio and a Message Center (both tap into the VSS signal). I know the 98+ radio is supposed to use an ABS computer-derived signal, so could it be fudging with the VSS?
Thanks!
