Hi,
I have had my 80 corvette for over 25 years and I have been noticing
the Tach has been acting crazy ? It acts as the car warms up the
tach goes higher and stays higher. Has any one seen this ? Is this
just a bad tach ? I looked around and I think there is a logic card for
the tach ? Any help would be greatly appreicated !
Thank you, WJDomery

Have you checked the wiring connection at the distributor? The only problem I've ever had with the tach in my '80 was a loose connection at the distributor.
