There are many things that can cause the light to come on. Generally if it is serious most 'check engine' or 'service engine' lights will blink. The simplest (and cheapest) method to diagnose the problem is to take the car to AutoZone and they will read the computer codes free of charge and tell you exactly what it is (such as the oxygen sensor got a bad reading and needs a reset, or its time for an oil change... etc.)

You will have to get the trouble codes read to find out what is causing the vehicle to hesitate and the check engine light to illuminate.
