if you are talking about the check engine light still being on after servicing the EGR valve, it will not go off on its own. it will need to be reset by a OBD II scanner. you can take the vehicle to autozone and they will reset the light for you. after the reset, drive the car normally to make sure that the problem has been fixed, and that the light doesnt come on again. it is a good idea to have it checked one more time before you take your vehicle in for state inspection. IT CERTAINLY CAN AND WILL RESET ITSELF AFTER AWHILE OF DRIVING

How many O2 sensors does a 2002 Saturn L300 V6 3 l have all together?
A 2003 Saturn may stall while driving due to several potential issues, such as a failing fuel pump, clogged fuel filter, or malfunctioning ignition system components like spark plugs or ignition coils. Additionally, problems with the engine's sensors, such as the crankshaft or camshaft position sensors, can disrupt the engine's timing and lead to stalling. Regular maintenance and diagnostics can help identify and resolve these issues. If stalling persists, it's advisable to consult a mechanic for a thorough inspection.
