Question about 2008 Ford Expedition El
The sulphur smell is the result of the emmisions control system. I have an 06 Expedition with the exact same engine and emmisions system as yours. When the engine is cold, you don't smell that sulphur smell, but as soon as the engine gets to operating temperature, the exhaust gasses smell sulphury. Nothing wrong with your ride - they all do that. The dealership sometimes spray the underbody with some type of rubber to protect the vehicle against rust. This rubber stuff sometimes get sprayd on the exhaust as well and then you will smell "burning tires" after driving the vehicle. This will go away after a few thousend miles though.
