I noticed when I am going like above 40mph, that after cruising for a while, the needle slowly comes down, like I am slowing down, but I am going the same speed.

For example I went on a decent trip, and the needle slowly dropped, to where it said I was doing like 30mph at 65mph, then eventually I was doing 0mph at 65....I had to use my tach to tell my speed.

After the car sits, the needle will work again when I drive it. Oh yeah it still counts miles when it stops working on the highway, so the cable IS spinning.

I did a white face gauge swap, but knowing hoe the internals work off of magnets, I'm kinda confused as to why it's not working like normal.
