Get the code, if you dont have a reader any auto parts store will read it for free...

I had this issue before. Check the code to make sure it is the 02 sensors. If so, you'll need to get the plug and play 02 conditioner from PPE. Or you can wait and get the RRRacing tune that would eliminate the CEL.

As others have said, get a code reader and find out what code it is throwing. Without the code, nobody is going to be able to help you. The code is going to provide some additional details as to why the engine is not happy.
