I replaced the vss because my speedo was bouncing around all over the place and when I replaced it, it stopped working so I put the old one back in and it was jumping around like originally. Well now it has completely stopped working. It would sometimes jump around for a second if I hit a bump but now it doesn't move at all, and all the rest of guages work fine. So can anyone help me out if anybody has had this problem, I really hate not knowing how fast I'm going
