CM Tach Problem on 1 91
I have a 91 Corvette basic 350. The tach shows about twice the RPM's
that I am actually running.

How do I get that fixed.

Thanks Rich ANdrews

HI there,
You will most likely need a cluster.
BUT FIRST, note any aftermarket changes to the wiring, ignition system and anything else done to the vehicle.
Allthebest, c4c5

CM Tach problem 91 Corvette
Thanks. I was afraid that the cluster was going bad. I was hoping that it was
something easy to fix.

Regards

Rich Andrews
