My tach when the car is off is stuck at about 4 thousand rpm, when its running it stays there until i get the car moving at the high rpm range at which point it just bounces around from the stuck point to hte redline...any ideas..... |confusing|

Sounds like the circut board for the tach is bad. This is a small board located in the instrument panel behind the tach. I replaced mine and now it works fine.

Good luck.
