Hi my name is ***** ***** I will be happy to assist with this here.

One common component that causes this here is the stepper motor that operates the speedometer gauge itself.This electric motor can short out or fail and cause the jumping you see here.If there is no running or driving issues with this fault here from what you have described the instrument cluster either needs removed and sent in for repair to an authorized repair center or removed and replaced.

Thanks Pete
