erratic speedo

My speedo is all over the place, sometimes in sticks to 180mph and doesnt move again. All the other dials are working fine just the speedo.
any ideas?

I get that, sounds like the de-limiter chip is breaking down.

Might be worth changing it or some people just buy full working second-hand clocks and fit them instead.

That's how I fixed mine (I was doing 180mph parked in my driveway, and sometimes 0mph on the motorway). - I just took the speedometer out of the donor clocks and swapped it with my broken one (keeps my odometer reading and the delimiter that's soldered to the back of my clocks).
