Default Tach problems-89 readout bounces around

This happened to me once before, where the dash tach won't stay steady, and bounces up and down 2 to 400 rpms. I remember that there was some sort of resistor or something that could be installed where the tach plugs into the distributor, that would cure this problem. Anybody know what it is and where I might get one?

Thanks for looking!

Steve

NEVERMIND! I found it! It's a tach filter. Thanks anyhow!
