Speedo was acting up this morning

[chillman88]

It was reading about 15mph high for a couple miles. Started out right then ran away for a little bit. After it sat it was fine. The video is the misbehaving and the picture is normal operation. Any clue?

Since it was acting up when cold Id reckon the cable needs to be lubed

I was thinking that but why would it spin FASTER??

Also... How does one lube the speedo cable?

Pull it out and hold it straight up and use a plastic nozzle to spray into the tubing while spinning the cable to help it work its way in, not as efficient as pulling the whole cable out of the tubing but its worked for me. Dunno why it would read faster, maybe the actual needle got stuck and it had to come to a full stop to work the kink out?

Spedo module in the cluster is failing.
My 90 just had it's second one fail.

Ugh I hope not. It was pretty cold so I choose to blame the cold lol.

If it truly is the speedo itself it will get replaced with a PSOM driven off the ring gear. I'll wait until it finally fails before that though. I do actually have a spare cluster in the parts truck though.
