Ok so i will admit this is my first Mustang and I'm a bit of a girl about things. (please laugh at me if I'm just being a worry wort) That being said i have noticed a slight tick coming from under my hood. I only notice it at idle slightly but when I'm starting off from a dead stop, as I'm letting the clutch out the tick is a bit more noticeable. I am running 91 octane which is the highest i can get in my area. Could this be a ping or possibly an exhaust leak? Perhaps something i haven't thought of? My knowledge of these newer high tech motors is quite limited unfortunately. Thanx in advance for any help. Btw this is a 2010 gt 4.6L
