Anybody had their tach go nuts. I was strolling along an noticed my tach had pegged out. Let off the gas and stoped. Tach was showing 4000 at idle. Gave a little gas and it would peg all the way out again. Shut off the engine and it stayed at 4000. Worked the switch on and off several time and it finally went back to zero and seemed to work normally after that.
