My 95 Grand Marquis check engine light which came on turns off and stays off a few days when the battery is disconnected briefly?

The computer is detecting a malfuction. The next time the light comes on, do not unhook the battery, take the car and have it checked for codes. You want to repair the cause, not ignore it.
