2000 Sunfire Horrible gas mileage, and erratic gas gauge
I have a 2000 Pontiac Sunfire, it runs great. I noticed that the gas gauge, would always move about in about a one inch radius, would drop and raise erraticly. I put 3/4 of a tank in it yesterday, drove about 75miles, and it had dropped to 1/4 of a tank. I have noticed that it didnt seem to be getting very good gas mileage, but didnt really think anything of it, until this. I just had the fuel pump replaced when I got it, as it was completely out. Any help, would be greatly appreciated. thanks! BTW, it is a 2.2 Automatic.
