I dunno what happened, but I started my car yesterday when I was going to drive home and I thought the car didnt start cause the tach wasn't working. So I tapped the gas and heard the engine, it was indeed on. The car runs and drives fine, what could cause the tach to just suddenly stop working? Also, when I start the car none of the idiot lights come on except for the battery light, but that goes off right away too.
