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.

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!
