I've got a similar issue, recently the tachometer will jump way up, even peg at 9K, right after start. It continuously reads high and is very unstable.

Very common in these cars. Mine is currently unresponsive at any operating condition. I just choose to do without.

Our speedometers break down because the solder joints break where the mounting screws are.
Re-soldering the joints fixes it.

I suspect that our tach has a silica problem, and a similar repair might help.
