You can go to autozone, o'reilly, advanced auto, etc
Usually they can retrieve the codes from your car for free.
If you do have a blown head gasket, it could cost you up to $1500 to have it fixed, depending on your engine.
So it is up to you to decide if it is worth fixing it.
If you do decide to have it fixed, make sure you go to a reputable shop; if a head gasket job is not done properly, the new gasket will fail prematurely.
Hope this help
