That's the computer's way of saying "read my codes". You can borrow, rent or buy a code scanner from most auto parts retailers. Any time the light comes on like that it's indicating that the computer has detected a "fault code" meaning that something is wrong. The computer can tell you exactly what it means. There really is no way to guess and be anywhere near accurate, but probabilities are: oxygen sensor, EGR valve, map/maf sensor, misfire or any of a number of potential problems. The computer is trying to give you the best possible fuel economy and minimize emissions. If the computer has detected a fault it will be unable to be as effective.
