On Saturday after a quick wash, I head down to Naples for the night. I'd say about 1 mile into the drive I notice a vibration at idle. Literally from one stop light to the next it started. Nothing noticeable while driving, only when stopped at a light or in park/neutral. Stopped at Autozone to see if there were any codes, no lights lit on the dash, and no codes were stored. The oil change indicator was already on, so I thought maybe it had something to do with this. Changed the oil yesterday before work...real fun, and no change. Vibration still there.
Anything I can check without running to the dealer? Could this be a vacuum line disconnected? Bad gas? But that would be noticeable under acceleration, right? PCV is new as are the plugs. BTW, 2011 HEMI
