What owners wrote

Rotten egg smell when the gas pedal is depressed quickly from either a standstill or already moving. I've tried all different types of gas but to no avail.

December 2003

When driving my 2004 toyota 4 runner emits a sulfur like odor. I have been told that switching fuels will help, but I have tried all fuels in the area of all grades and still have this terrible smell. It happens on a repeatable basis, most of the time after exiting the freeway onto a surface street is when it is most noticeable.
