How do you know nothing is wrong with your engine? Have you extracted the codes from your computer? More likely than not something is going on that you may not be able to detect with everyday driving. Could be a MAF leak, bad IAT, bad oxygen sensor...or the dreaded bad computer.

Like the other guy said...OF COURSE there's something wrong with your engine. Well, more specifically, there's something wrong with your engine's computer system.
That light can flash trouble codes, to tell you which part of the system is having trouble. There is a technical article on this site about how to do it. All you need is a pen, paper, a paper clip, and five minutes.
After that, though, you don't just go and replace the suspected part, unless it's cheap. You should first check all the wiring connection to that part.
From what I remember, if the light takes a long time to come on like that, it's likely to be the oxygen sensor, or maybe the throttle position sensor. Regardless, GM recommends replacing the oxygen sensor every 30,000 miles anyway, and most people don't bother. So if you bought the car used, it's a good idea to replace the sensor. They're cheap, but a real pain to replace sometimes.
A faulty oxygen sensor will also cause you to get lousy gas mileage. And a new sensor costs about the same as one tank of gas. So it wouldn't take too long to get a return on your investment.
At any rate, the last thing you want to do is "disable" the light, which you can easily do by taking the dash apart and removing the bulb.
