During the hurricane I was unable to use regular gas. I was using the high end gas. Now my check engine light is on. Does this have anything to do with it. Also my back brake light is out. Cause this be why my check engine light is on?


Your check engine light should not come on because you used higher octane gas.

Stop by at an auto parts stores and read the codes. Let us know what they are.
