I just made a run into town and the Check engine light/emission light came on. Uh-oh i just got this 05 m6. so i ran over to Advanced Auto and they ran a diagnostic check. THe error message came up that said "Emission system High Purge Flow". is it because my dumbass put 87 instead of 92 octane in it? or is it something that should really be worrying me?
