You do not reset the check engine light on that year of sunbird, it will go off automatically whenever you fix whatever problem the computer is reading. Most likely it is one of your sensors that is malfunctioning. Check your Air Intake Temp Sensor (AIT) and your Oxygen Sensor (O2) as they are the most likely culprits.
