A buddy of mine has the " Snap-On" diagnositc unit. Normally when I drive, there is no reaction from the Speedometer until I hit about 40mph where then it jumps to 60 in reading. The Snap-on diagnositc unit showed differently. As I accelerated from 0 on up, the speed reading where correct.
So, this is why I have elimated the Speed Sensor, the ECU and the wiring between the Speed Sensor and the ECU. Last causes left are the cluster and the wiring from the cluster. I did change the cluster, possible the replacement is bad too, and saw simliar results. This leaves me with the wiring from the cluster to the ECU. Boy I hope it is easy as it sounds. LOL
