Zero issues and no check engine lights but my exhaust started stinking really bad yesterday. The smell is hard to describe but it lingers for a long time. Anyone have any clues as to what it could be. I was thinking bad gas or water in the gas. It is definitely coming out of the exhaust and the only thing I changed was adding fuel from a local Chevron the night before. 93 Octane.
