Hi all, my speedo is getting stuck at various places randomly on the dial. Suburb cruising 40 sometimes 60km/h. Freeway at about 80 no higher. It was working perfectly despite the car being driven lately maybe once a month over the last 6 months (don't think that should effect it).

It happened after I replaced dash with a new one, took all gauges out and then replaced after. Cable is all good and fine at hub end. Cable runs via speed sensor as I'm running a Suby engine. Can't think what I've done wrong. Took gauge out and turned over with a battery drill with and without speed sensor, still getting stuck.

Any ideas?

Sounds like the drag cup is hanging up on something. Either a speck of dirt or bit of oxidisation.

You'll have to crack the speedo open to inspect the drag cup and the tiny speedo spindle.
