    The check engine light doesn't have to be ON to store a fault code.

    Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

    1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

    2. has the code reader for less than $20.00 dollars.

    3.Re-post the dtc's in here " answer question " for further assistance.

    Note: we need the dtc's to identify the sensor, there are a dozen different sensors to operate the car.

    Visit this site and see all the different sensors.

    Navigate to this site and see the code reader

    The doc was reading nothing it says my car is fine but that's not true so what do I do when no codes show up

    Verify the base timing is within specifications. The timing belt might jump and i don't have enough data about this Epica.
