Default Why does my tach twitch?

I've got a 92 si. Why is it that my tach jumps around, about 500 rpms each direction? The engine itself is uneffected; it is only the gauge that is acting screwy.

How can I fix it?

Thanks.

Another one people overlook is the ground by the thermostat housing. That will Definately cause a twitchy needle!!!

I think it might be my connection at my vtec controller. The tach on there looks fine and doesn't twitch at all.
