Hey everyone,, I thought Id pop a question in here, Has anyone ever seen thier speedo gauge bounce up and down like 0 to 20kmh with just the engine running and the car not moving. Mine does and if i rev the engine up the speedo bounces higher, sometimes as much as 60kmh. Also my odometer slowly ticks over (cause it thinks the car is moving). I bought this car a couple years ago and the previous owner mentioned it too me, so its been doing this for years. I have checked all the connections on the back of the instrument cluster and everything was tight fitting.
Thanks
Ken
