Check engine light on
Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.

Go to Autozone they'll scan it for free-

Raz is correct, have the scan performed and it will tell you the next step. Driving it wont change the fact that the light is on.
