Malfunctioning emissions system. Get this repaired. Engine probably running rich from a leaking fuel pressure regulator. If there is fuel in the vacuum line the regulator is bad.

Car exhaust can smell like rotten eggs when the fuel has a lot of sulphur in it.

Most likely your exhaust is rattling and the smell is because your catalytic converter is bad

No, the smell of rotten potatoes is just a smell that nobody likes.

You may have an exhaust leak. Better get it checked out. Any exhaust leaking into the cabin/passenger area can be potentially hazardous and deadly.

Some farts smell of rotten eggs because they contain Hydrogen Sulphide - which is what gives rotten eggs their smell!

proscuitto shouldn't smell rotten, it should smell salty and just a bit meaty.

probably the catalytic converter- or you child is smoking in the car

A rotten egg smell is usually a sign of a failing catalytic convertor and also at times failing oxygen sensors. try the cat first and that should alleviate your smelly problem. answer before you change expensive catalictic converter, try using a different brand of fuel sometimes fuel company additives will make your exhaust smell like rotten eggs

There isn't much a person can do to stop the stinky smell of exhaust from the muffler. This smell, sometimes like sulphur or rotten eggs, is a by-product of the fuels burned.

Because the smell is added so it can be detected. If natural gas smells like rotten eggs then it contains H2S or hydrogen sulfide. Actually the smell associated with rotten eggs is hydrogen sulfide, so hydrogen sulfide does not smell like rotten eggs, rotten eggs smell like hydrogen sulfide.

Don't know exactly what you mean, if the rotten egg smell probably cat. convertors fuel smell probably ox. sensors. Does it still idle and run smooth?

The sulfur in gunpowder makes it smell like rotten eggs.

That rotten egg smell is most likely emanating from the catalytic converter.

User Avatar

A part of your exhaust system, the catalytic converter, has stopped working correctly. You need to get a new one.

Eggs do not smell at all but however, when they are rotten they tend to do smell.
