Diagnostic code comes up to say emissions leak and was told preferably to change gas cap, but when I did replace the cap, I unhooked the battery thinking it would reset and if the problem had been resolved then the check engine light would not come back on. Not the case, however, because the light came back on and I am again looking for a resolution.
