2010 Dodge Charger Question: Why is my check engine light on?car is running great.
probably the gas cap is the problem, without the check engine light code its just guessing. make sure the cap is correctly installed when refueling. - FREDDY BLUE

Is it the original cap? Have seen some aftermarket's that dont fit so good. Do you know if it had an EVAP code? - pushrod
