Go to junkyard, get complete cluster, take out your cluster, replace tach
part, only.

Uh... you didnt SAY if the engine SOUNDED like it was idling fast, so i
assume it doesnt.

If it DOES idle fast...then you likely have either a failed sensor or a
vacuum leak.


That said, IIRC, the tach-flip syndrome USUALLY goes to about 3500.

I took the cluster out today and made sure that all the plugin connector
strips were clean and shiny . After I put it back together again it
worked fine for 1/2 hour and then jumped back to 2000. The car is idling
@500 as per usual. Can I change only the tach part of the cluster?.
Looks like it's all one unit. Since I'm driving around with the cluster
torn apart, I can see the switch housing and wires for the headlamp
switch. Do these wires normally run warm/ very warm when the lights are
on. Anyway thanks for your help. Cheers

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.

This is the reason you see so many Mustangs with Autometer tachs
added on.
