You can reset the short term fuel trim by disconnecting the battery for a couple of minutes.

Why don't you just...stop driving it in an aggressive way?
The computer adjusts to how you drive it, just drive is more calmly and more gently and it will adapt. There's nothing to reset to zero. Besides, if you drive aggressive all the time, your MPG will suck anyway. |

Ahhh.. Fuel trim huh? this would explain why it seemed my car ran a little differently for a while after I replaced my dead battery but has since "cleared up".
I drive a little aggressively most of the time and my ultraguage says I'm averaging 35.2 MPG.
