Ok, everyonce in awhile, ussually when its sorta warm out and i take my car above about 4500-5000 rpms, i get a sulfuric rotten type smell coming from the engine. Driving my dads 03 Aviator a few weeks before i floored it to like 6000 and it had the same sorta smell. Does this mean that maybe the gas we've been getting in the area could have been bad? Or was that just a coincidence? Anyone know what it is?

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.

It may not be a bad Cat.The old sytle cats used to be a type of pebble meduim that cause the reaction for the cat to work.When the meduim went bad it would no longer cause the reaction so you would smell a rotten egg smell. But with the new style honeycomb cats they are much more efficient. Your car has a preset fuel curve for full-throttle that is part of the cars PCM programming. So the car injector on time is set to run slightly rich to reduce any possible detonation. You might check the air filter and inlet for restrictions. The cat should be able to handle slightly rich fuel mixture. But with a restriction you have to much gas and not enough air in the mix. A good test to check your cat is to purchase or borrow a Hand-held infared temp sensor . Drive the car for about 10 minutes at 30 miles a hour then point the infared sensor at the cat if you get a reading of 500degrees the the cat is fine if lower than cat may be on its way out.
