I've read what Frodo says too... that if the CEL light is flashing, it's something that warrants you not driving the car anymore until you can get it looked at. If it is a solid light that doesn't go out, then you can continue driving it for a while, and get the codes read to see what the issue is.

You should get the code read (either buy a code reader at an autoparts store, or bring your car to a shop where they can be read). Once you get the codes, you can then determine what might be the problem. Good luck.
