When the light comes on it's because the computer senses a problem with the engine control system. One or more trouble codes would be stored and accessable to your machanic. I wonder if there's a sensor wire unattached, an intake air leak or something like that. BTW, they should tell you what the trouble codes are and what's wrong. If they don't, you may need to see another mechanic. here's a directory link for you:
