On the gauge cluster with Tach/Fuel/Coolant temp yesterday where the miles indication is, it reads Er IU and the coolant temp and fuel gauges would drop all the way then jump back up to where they should be. Also the red lamp that indicates if you open a door/the trunk lid would light up with the gas light when the fuel gauge would drop to E. This gas light problem only ties to why it seemed to be malfunctioning.. i have 3/4 tank of gas.. no leaks i think the instrument panel is just malfunctioning hence the ER IU on where your miles are displayed.. anyone??
