When I start my truck, the guages all go the right then immediately back to the left. For example, my speedometer will go to 120mph and then back to 0mph. This used to happen occasionally but more recently, happens almost every day, especially after the car has sat for a while.

Anyone know why?

Thanks,

Test your battery, I bet it needs to be replaced. Dead (pun intended) givaway on these trucks when the guages start doing that.

 

Just replace your battery. It's on its last legs.
