I had the same problem and it was a bad plug wire. It would make the tach jump around very eraticaly. The only thing I could figure is was sending some kind of pulse back through the ground but who knows. Mine was a Mallory tach with a Unilite distributor so it might not be your problem but its worth a try. Hope it helps.

I agree with SO. Faria gauges are not that great
