If your check engine light is on and it's running rough then it could be due to a bad PCV valve. This valve controls crankcase ventilation it helps to remove the harmful gases from the crankcase. If it is damaged or broken then it will not work correctly and cause your vehicle to not run properly. This valve will need to be replaced to make your vehicle run properly. Give us a call and let us take care of you.
Happy Adventures,
