Sometimes my tach will read too high... say 2000 rpm at idle... and 4000 rpm while just cruising. Sometimes I've tried smacking the side of the tach, and the reading will go back to normal (maybe it realizes its misbehaving and doesn't want to get hit again). Other times its stubborn and continues its bad behavior. But most the time the readings are just fine.
Is this likely an issue within the tach, or is this more of a wiring issue somewhere between the distributor and tach?
