Re: 93 Mustang tach shows 2000 rpm at idle. seems like 2000 rpm is the new zero???
If it's like I recall, the tach head can be removed from the plastic
substrate and housing.
Mine had a bad elect component in it... yours may have a bad connection
inside head... all tach components should be in the head. The
housing/substrate has only wiring traces.
