It's not uncommon to smell that rotten sulfur smell after driving the snot out of almost any new car these days. Don't worry about it on the Aviator. How old is your car and how many miles does it have on it? If it's new, then I wouldn't worry about it either. As cars get older and increase in mileage (usually 90-100K sometimes less), you may have to replace the cat. converter. It's the same with O2 sensors.
