Abby, the check engine light being on could be due to so many things that it is not practical to try and list them all, for the sake of our conversation, the best thing to do is to have the scan done by a qualified service center that you can feel good about, one that you trust. The light could be on for low fuel level or a bad spark plug or dozens of things. To answer the tune up question, a general inspection of the car for work needed and for safety should start at a reasonable diagnostic charge of about $75-$100. Then the service writer should be able to have the price broken down for each step of the work. If you need help in this process, come on back.
