Under what driving conditions does it come on? Or does it come on immediately after you start your car?

What year is your car? I'm guessing either a 93 or 94. Odds are you probably have the same problem as stoned and I. Does the light normally come on the same way stoned mentioned? If so, then it is your EGR. It's a very very common problem on the 3.4's. If this isn't the case and your's comes on under different conditions, then it is very hard to tell as to why. Your best bet would be taking it to a dealer and have them scan it. Or you can buy something like this and scan it yourself:
