Check Engline Light is on reading the EGR has a problem.

(1999 Mercury Cougar)
Check Engline light is on, i took it to an auto zone so they could pull it up on the code reading device, and they said its reading p420 or some number that started like that. and said it has something to do with the EGR. My car runs great and sounds quiet. could this seriously hurt my car if i drive it very far?

It probably wont damage the car, it will just emit more emissions than it should. You can learn all you ever wanted to know about the P0420 Code here: http://repairpal.com/OBD-II-Code-P0420
