As you can see I’m driving by my speedometer, but randomly the tac shut off and slowly glide down to zero while driving, and then all of the other small gauges jump to the middle position. The gas gauge no matter how much gas is in the tank it will spike to the middle of the display. I’ve started to notice it does this when the engine get hot, and will do it on start up when it’s about 90’s outside. How do I fix this!
