Am having the weirdest problem with an 02 Ford Focus 1.6L Zetec - at random times and random speeds the speedo starts jumping up and down for a couple of seconds to a couple of minutes and in fact does not stop until the car's engine has been switched off or is idling,
Has anyone out there experienced a similar problem with a Ford or have any idea what may be causing it. Investigations by my local garage confirm that this is not an electrical issue.
Cheers
Cat
