My dads would jump up to 2,500-4,000 when it’s idling at the normal idle. Sometimes tapping it would bring it down to the normal range and would still be inaccurate. I do it sometimes when bored after the car is off. An answer would be nice lol, maybe I’ll be able to fix that.

I have had two Fords (one Mustang, one Mountaineer) do this over the years. I ended up replacing instrument cluster on both. Before replacing, I tried removing the instrument cluster and looking for broken solder connections, I cleaned and cleaned again all of the connections where the wiring plugs in the back of the cluster, no luck.
