SOURCE: 2006 Toyota 4Runner Sulfur smell

I noticed going from a Higher Grade gasoline as well as making sure I change my motor oil on a regular basis (3,000-5,000 mi)to solve this problem. When the car isn't driven at a high RPM for a while, and you go to a quick acceleration it causes this smell.

SOURCE: smells gas after idling

The fuel pressure regulator may be bad and leaking gas on the intake manifold. It's a cylinder shape with a vacuum line and it's connected to the fuel injector rails. When the diaphragm goes bad in the regulator, gas will leak from it and on to the engine, which give you the smell of gas through out the car when it's running. Good luck and keep me posted, Auto Zone sell them for around $15.00 and that can give you the step by step instructions with common tolls and takes about 15 to replace.

SOURCE: Sulfur smell and rough starting is noticed and

this could be a fuel filter issue, but more than likely it sounds like a broken down / clogged catalytic converter. to confirm, have an exhaust back pressure test performed. this is a specialized gauge that threads into the oxygen sensor fittings and will tell you if there is excessive restriction. if you plan on keeping this car for a while (more than a year) i recommend using a genuine GM replacement, as the cheaper ones do not last long at all. in any even, it is good idea to change the fuel filter first. good luck!

Engine stalling

The sulfur smell is usually low grade gas or a problem with the catalytic converter.
In your case I would go for bad gas, especially if the problem just started happening recently. You can try adding premium to the tank and drive it out. You may have to replace the fuel filter once or twice if the gas has water or other contamination.

Funny smell like egg vinagar in focus 08 model started when sitting in traffic

I'm going to assume the smell was coming from the exhaust.
Sulfur smell is often caused by excess sulfur in gasoline or a problem with the emissions system on the car.
If the check engine light is not on, it could be the brand of gas you were burning at the time.

Stalling ford ranger

There are a few things to check, first make sure all sparkplugs ,plug wires are good, in other words make sure engine is running smooth, a misfire will cause the smell and stalling so make sure tune up is not the problem first.

The next thing to check would be make sure air filter is good and throttle body is clean.clean the plate and body around the plate, the oxygen sensor can also cause this problem and is often forgotten about, the last would be the idle air control valve that control idle , there are more things that can cause your problem but start with these.

The most common problem may be as simple as the coolant temp sensor, this sensor if giving the computer a false signal with wrong coolant temp then this will cause this problem also.

A scan tool or multi- meter would help in testing the coolant temp sensor. hope this is helpful, good day.

2003 Mitsubishi Lancer ES. First had code, changed both O2 sensors. Bad sulfur smell resolved, check engine light resolved for about 400 miles, then came back on. Same code, but the smell is still gone....

Probably a bad catalytic converter. Causing back pressure and making your O2 sensors read wrong. Cheap gas of less than 87 octane can cause incomplete combustion giving the sulpher smell and leave deposits in the exhaust. The sulpher smell originally came from fuel additives in your gas. Cheap gas especially. Your converter puts it out as sulphuric acid. This damages the sensors and converter. Ultimately though, what cause sconverter failure prematurely is idling your car for long periods. Over 3 minutes is not recommended.
Thanks, Mike.....Please rate the answer!

Rough idling, poor gas milege

Usually the rotten egg smell is a clogged CAT. Is the engine light on and if so did you retrieve any codes?

you haven't said if its petrol or diesel so i'm assuming its petrol since your smelling sulfur sounds if you have a misfire causes could be plugs,leads or ign coil i suspect its ign coil these are common to go.
