Is your check engine light on? If the cylinders were not firing properly it would trigger a code. If so go to aotuzone and they will pull the codes for free and give you a printout of the codes with a slight description, Then let us know what they say.

If you changed the battery because the old one was weak (maybe dead?) there is a good chance that the ECU was relearning fuel settings that were lost when the battery was out. That may be the reason for the temporary rough idling.

For now, just keep an eye on it and let us know if the rough idle returns.
