Hi there. Unfortunately, without knowing what type of error code caused the check engine light to illuminate, it’s difficult for us to give you an accurate recommendation of repair. It might be a good idea to have a professional mobile mechanic come to your location and complete a check engine light inspection; then ask them to tell you which error codes are causing the error light and what repairs are needed.
