2014 Mustang GT engine idle issue

Hey community,

I'm troubleshooting a possible vacuum leak after a warranty engine overhaul ( due to the 5.0 tick ). In fact I think I'm even able to hear the vacuum leak when like sitting at a drive through. The dealer refused service so I can't go back there.

My question is for people who have a 2013-2014 Mustang GT Premium. I'd like to know what your air to fuel ratio gage is reading at idle. Mine is bouncing between 13.8 to 14.3.

Can you guys look on your cars and post back?

Have you addressed this with your dealer, trackpack13gt? Will you PM me and let me know what has transpired so far?
