A few weeks back my tach was acting erratically, where it was jumping all over the place and not giving an accurate reading. Happened for a couple of starts for a few seconds at a time until the car was shut off. Tach connector was unplugged then plugged back together and the issue stopped for now.

Anyone else experience this with the Speedhut gauges? Trying to determine whether it was a one time fluke with the plug or if there is something else going on. I’d like to resolve before the body goes on for the last time. Thanks
