Something thats been bugging me lately is the fact that my gas gauge on my 00 gtp is a off by one or two notches(high or low) everytime I start the car. After a couple minutes it settles and reads correctly. I know in some cars they have a module in the car to keep the gas gauge stable when turning and/or going up and down hills and I was wondering if our cars had something like that and maybe mine is going bad?
