while driving the spedometer and rpm needles*****. Also on right hand curves it does this also.This seems to happen when the weather changes. I have had it checked out a few times and nothing can be found. I am wondering if it could be a sensor or if i keep heat in it if it would help. This has happened on and off for a few years. This car is a 2001 pontiac grand prix 3.1L
