Sometimes the tach just goes wild. It may peg at max rpm's, or bounce back and fourth. I've installed a new tach amp (round thing on drivers fender), and replaced the original tach with a used one. The problem is the same. I need some help guys. Any ideas? Thanks in advance.

You have a ground problem or loose wire. You will have to check from top to bottom. Do you have a ETM? (electrical troubleshooting manual?)

They are in the CD we offer in Partsshop.
