Hi:
If you just replaced the battery, allow some driving time to allow the computer to relearn the system. If that doesn't help (100 miles or so) have the computer scanned for codes. It may have something to do with the throttle position sensor. Let me know what happens.

NOTE: Most nationally recognized parts stores will scan the computer for free.
