Incessant Burning Fart/Rubber Smell
Hey all, yesterday i was driving my car a little aggressively and peeled out, only to receive that horrible burning rubber smell. Or so i thought. After about 2 hours, i came back to my car and the smell was still there. It was trapped in the inside of my car. I drove home with the top down and the smell seemed to go away. However, throughout the rest of the night, when i was driving my car, it would make a horrible, fart smelling stank every time i put it in gear and started driving. I have had a hard time trying to locate the smell because when i turn the car off, it almost completely goes away. The engine compartment doesn't seem to smell, the brakes and the tires don't either.
So all of that got me thinking, and since my clutch is almost entirely burnt out (going to replace it in the next month, but i haven't had any slipping problems yet), i was wondering if this could be the cause of this horrible smell, perhaps due to the clutch slipping on the flywheel incessantly. Has anyone had this problem, or know what is causing it??
Thanks

Does it smell like rotten eggs?

Fortunately, most cars never emit the sulfur odor but those that do can trigger a tearful experience. To make matters worse eliminating the odor can be difficult and in some cases nearly impossible. An incurable odor that can bring tears to your eyes is not an amusing Commercial Three Bayspect but with some vehicles it may be part of the driving experience.
The odor comes from the retention of excess sulfur compounds in the catalytic converter. Sulfur compounds may be the result of highly blended, additive-laced, oxygenated, reformulated gasoline. Here’s how. Cars now have three-way catalytic converters, which tend to store sulfur leftover from burning gasoline. This typically happens while the vehicle is being driven at steady highway speed. When you slow down and re-accelerate or the engine comes to an idle the air-fuel mixture becomes more concentrated with fuel. The richer fuel mixture creates a chemical reaction that leads to the release of stored sulfur in the form of hydrogen sulfide. It’s the hydrogen sulfide that has the nauseating smell!
Although odor may be normal for some vehicles simply changing brands of gasoline might make it acceptable. No, this doesn’t mean one brand of gasoline is better than another but rather that slight differences in formulation can alter exhaust odor. Also a gasoline that works well at reducing odor for one car may not on another. Cars, car components, and gasolines are now so technologically developed that miniscule differences in gasoline additives combined with an un-measurable lack of a chemical in a catalytic converter can lead to smelly, rotten egg exhaust odors.
But, the Commercial Three Bayblem may not be affected by gasoline brands and therefore require repairs to correct. If the odor happens most of the time and not just following a highway cruise you may have a fuel mixture Commercial Three Bayblem or a bad catalytic converter. Either can set the same conditions in motion.
Newer vehicles are designed to operate on a very specific air-fuel ratio. Fail to Commercial Three Bayperly maintain your vehicle and any one of several components in its electronic fuel management system can fail upsetting its air-fuel ratio. Sulfurous odors can often be traced to one of the sensors used by your vehicle’s computer to maintain desired fuel control.
The catalytic converter uses various noble, precious metals to perform its emissions reduction and prevent odors. Exotics like platinum, palladium, and rhodium. If too little of one of these precious metals was used during the manufacture of your converter you may experience odor even though fuel mixture is correct. A deficit of catalytic reaction compounds can cause a converter to drop below the minimum threshold for odor control.
So, if you routinely experience a rotten egg stench from your exhaust, try different brands of gasoline. If that doesn’t work, have a skilled technician check fuel mixture, tune-up, computer, and catalytic converter. When everything is functioning Commercial Three Bayperly there should be little or no noxious smelling hydrogen sulfide coming from your tailpipe.

Lol Yeah, well i wouldn't call it wining the lottery or anything. Yeah i did just switch gasoline, picked up supreme from Chevron when i usually get premium from Cosco. However, i don't think that explains it because it is definitely not a nauseating smell. So its probably just the clutch, which sucks cuz i need to replace it but its also my only car, luckily Nissan does rentals.

Before i even clicked on this thread, just by the title i thought in my head.... clutch.... but if its smelling like you say it also shoudl be slipping... another more unlikely cause of the small is plastic... few months back i was drivign on highway and drove over a plastic bag which somehow got tangled and melted onto my exhaust and for the next month my car smelt like doo doo after running for more than 20 minutes..... but its probably jsut the clutch

like everyone else its your clutch, im in the same boat its not slipping(at least noticeably) yet. but when i work the card hard i can smell it. i know mine will hold out till spring, just not sure if i should try and hold out till the end of the first track day so its totally trashed or replace it before
