Computer Reset???

[gofus72]

I had to replace my battery 2 wekks ago and ever since I did that my gas millage went down hill. Do I have to reset anything like the main computer in the car to get this problem solved???

The two have nothing to do with eachother. Battery doesn't increase or decrease gas mileage.

I don't know about mpg problems, but whenever you reconnect the battery (after having it disconnected for some time) you should start up the car and let it idle for a couple minutes. Even if you don't do this, the car will "relearn" everything in a couple dozen miles, not two weeks of daily driving.
