After disconnecting the battery in order to service a problem you may encounter stalling or other issues while the computer relearns idle. If you continue to have running issues after a couple days of driving then you will need to have the vehicle checked by a mechanic like one from YourMechanic to test the computer and theft system for possible problems after you disconnected the battery.
