I noticed this last night, I went to walmart to get a new key cut, and when I came back to my car, this started happening with the new key. Of course, I was like WTF - so I turned the car off and started her up with the old key - temp and gas gauge went back to normal.
This morning, I started my car and let it warm up, and my gauges were normal (normal being temp @ halfway mark and my gas is EMPTY)
I drive about a mile out and the temp gauge starts creeping up again, same with my gas gauge. So I pulled over to take this picture.
Also, my car isnt actually overheating either. What do I do?? :/
