Lately my tach has been acting up. While the truck is running sometimes it drops down to 0, then if I hit the gas it will bounce back up. Sometimes it just flutters up and down. Seems like maybe a bad connection somewhere, but I don't know where all the components are. Anybody have any knowledge on this? What would be the most likely cause?
