Ignoring this light could lead to further damage to your engine, reduced fuel economy, or even complete engine failure. You should have the code read as soon as possible. You can do this in a few ways:
* OBD-II Scanner: Buy a relatively inexpensive OBD-II scanner (available at most auto parts stores). Plug it into the car's diagnostic port (usually under the dashboard), and it will read the trouble codes stored by the computer. This will give you a much better idea of the problem.
* Auto Parts Store: Many auto parts stores will read the diagnostic trouble codes (DTCs) for free. They can then help you determine the likely cause of the problem and advise on repairs.
* Mechanic: A mechanic can diagnose and repair the problem. This is the most expensive option but often the most reliable.
Without knowing the specific trouble code, it's impossible to say what's wrong with your Windstar. The problem could range from something minor (like a loose gas cap) to something major (like a serious engine malfunction). Don't delay getting it checked!
