I have noticed recently after pulling in my garage that it smells like sulphur.What could cause this?I use only chevron gas and use fuel injector cleaner once a month.

could be your catalytic converters going bad as well they put out a harsh smell under load when they get ready to kick the bucket

+1 on the cats going bad. That's usually the first sign.

Or it could be as simple as a lot of carbon buildup on the valves and intake.
I have no tune on car and run 87 octane Chevron gas,I was using 93 for the first few months.What can I do to clean the valves injector cleaner?And the car only has 50k miles on it doubt the cats are bad.

A burnt clutch will usually smell like burnt hair, not sulphur. Bad cats are usually what causes a sulphur smell...almost like rotten eggs. But it's probably not cats with only 50k on the clock . I'd run a bottle of the piss yellow gum-out in the tank before doing anything. Then I'd go after the EGR valve.

brake rotors smell like sulfur when your have to slow down from 100 or so, or even 70 to 30 and the smell can last for a bit

Hmmm, just about every car I have owned has had the odor if I run it ragged. It's usually worse if I have babied it too much...then run jump on it. I thought this was pretty normal.

i still say a clutch............it makes perfect sense, you run the car hard, and then there is a smell......it probly is not a major concern, since a little clutch smell is normal after driving hard, launching the car hard, etc..........i know i smell mine after most runs on the strip, not too much, but a tad bit when i get down at the far end of the track. a clutch smell does not smell to good if you have ever smelled a really burt one.

i guess i wouldnt worry too much about it unless you feel something weird or check engine light gets thrown up, i guess it wouldn't hurt to ask ford to check out your cats for you or the clutch, but i wouldnt waste the money.

When you smell this smell is it in the rain??
