iv had this problem for a month but it just started bothering me. Its not the car over heating its just when warming up if there is bumps in the road you really see the needle bouncing a little.. it kind of settles when its at its operational temp but is still a little loose i can slightly see it move..

what could the problem be? i know i will have to take the cluster out but before i can take a look, but maybe someone has an idea of what may be loose or broken.

thanks
