Sometimes my tach is fine. Sometimes it sits at 0 rpm until I pass 40 mph, then it jumps to 5-6000 rpm. Then it stays high a while, and drops back to 0 when I slow down again.

Is this just a matter of cleaning all the contacts on the instrument cluster, or is something well-known and even more evil afoot?
