The check engine light means that something in the engine electronics, such as a sensor, is not allowing the engine to run "closed loop". Ignoring this problem will mean that a) the vehicle will not pass the next smog inspection, if you live in a state like California, and b) you will likely get reduced gas mileage and possibly performance.
Take your car to a service station, or dealer, to hook up to the engine computer to ask what the problem is. It could be that you need new oxygen sensors, for example. You can do this yourself if you can get the right equipment to connect to the computer. Some places rent this gear. [Oh, I forgot to mention that some cars are designed to automatically turn this light on every 100,000 miles (or 50,000) just to get you to the dealership to have it turned off, for a small inspection fee, of course]
