Hello,
I Just bought a 1989 Z24 Cavalier with the 2.8L and the tachometer is reading double. Can anybody give me some ideas how to fix this?

Thank You
Dave

I assume you have a digital dash and if so it appears to be a common problem related to the cluster circuit board.

I do have a digital dash but the tach has a needle. I don't know if it runs off the cluster circuit board? Thank you for the reply.
