So i have been having an ongoing issue with my speedo, the speedo jumps up and down, i replaced the sensor 2 times no change, recently i noticed when i turn left or go over a bump it goes right down to 0.

Anyone had this issue before?

 

Check the plug on the back of the speedo and dash , they get loose or the wiring goes bad back there . you can do a search on how to repair the wiring if that is the problem .
