Tach Abnormalities

[<wolfbj@bellsouth.net>]

Listers,

My tach on the 71. On the way to work this morning everything indicated fine. 
Just ran down to the store, started the car, tach zoomed up to 3000 rpm and 
idled there.  The engine idle was normal, about 950 - 1000.  As I drove, the 
tach response was slower than usual.  I shifted like always at about 5000 to 
5500 by engine sound not by the tach, but the tach was reading 5000 - 5500 rpm.

What is up with the tach?  Any thoughts.
