Tach Dancing? ('95 240SX Base KA24DE Stock)

[Mycah Leonhart]

When the car is started - The tach dances like crazy but after warm up it chills out.

Why in the world is it doing this?!?! - It's not much of an issue right now cause the car I'm getting is an automatic so it won't be a problem for a month or 2 till I have the cash to swap the 5 spd in but it's annoying the heck out of me! - it's the only real flaw in an other wise perfect '95 Base Model.

Any help would be great, thanks.
