Every so often - intermittently - while slowing down coming off the interstate - or in any deceleration from a high speed (65+) my speedo will hesitate at one point and jump back and forth like it doesn't know how fast to read...

Example - doing 80 mph and let off the gas - then while slowing it will hit 70 mph and jump back and forth for a bit - then jump down to say 65 - do the same thing - then will go on down like normal.

It only does this at higher speeds - and like I said it is intermittent - not an all the time thing.

TIA.
