I have a 87 TA with a digital dash. 80% of the time I drive it the odometer isn't showing up so its not recording miles. When the mile are showing the odometer is working and recording the miles.

I am sure that many people might love this to pull a skam when trying to sell their car, but it is just an annoyance to me.
Please help

 

did u ever find out why ur odometer didnt work ? cuz i am having the same thing starting with my car
