Check your cabin air filter, it might be dirty and due for a change. It's located somewhere under your glove box on the dash board.

is your check engine light on?

Waoh,what a question? The check-engine light may be unrelated to your current issue but asking what it means shows you just want to drive and care less about the operation of your car. FYI, that light tells you about your car what diagnostic of health symptoms does for the human being.

toyota released a technical service bulletine - TSB on the issue.
google it. its a sulphur smell a very common problem on certain models of 4runners

an exhaust odour that smells like rotten eggs is the result of a rich air/fuel mixture. The
catalytic converter is responsible for reducing the carbon monoxide and hydrocarbon
levels in the exhaust. When the air/fuel mixture is too rich, the catalyst cannot convert all
of the additional fuel in the exhaust. The result is a foul odour that is often associated with
rotten eggs. If the vehicle only emits this odour under a heavy load or acceleration, the
symptom is normal.
