When sitting at a stop your speedo goes from 80-160mph, So is this the what they diagnosed as a speed sensor? My 2000 SE V6 has done this intermittentley for about a year now. I am convinced it is a charging issue(maybe a loose ground) with my car, because it only does it once in a while, usually with a high electrical load such as the a/c on high or something. As asked before, what spped sensor did you replace? The Vehicle Speed Sensor would control your speedometer and it is located above you right axle shaft and behind your rear exhaust manifold.They are a PITA . Is this the one you replaced?
