My Speedo was bouncing around for a bit and finally stopped. Thus far I bought and replaced: 1. The angle drive (it was bad) 2. The dust cap (it was worn) 3. The lower cable (Recommended by John Hervey)
We replaced all of those parts and the speedo still is not working. Yesterday we took the old lower cable and connected it to the bottom of the LAMBDA and did the drill test, the speedo does not spin thru the LAMBDA.
When I take the Upper cable loose from the lamda I can hand spin it and see the speedo moving.
Would this mean the LAMBDA unit is bad? Anything else anyone can recommend before either buying a new/rebuilt LAMBDA or buying that bypass long cable available for $89.95?
