I recently bought a brand new 2003 Toyota 4Runner and can not believe that it is normal for my brand new SUV to smell of sulfur. I was advised that this was due to poor gas being provided in our area, however I have driven from NC to VA to OH to NY to PA and back to VA and then NC and tried different types of gas and octane levels in each state and it made no difference. I now have 5K on my SUV and the sulfur is just as bad as it was when I purchased it. Why is it that I do not smell the sulfur in other vehicles, but only mine? A friend just bought a brand new Ford Explorer and his SUV does not smell like sulfur. I have questioned the dealership about this and they are convinced that it is not the catalytic converter and that it is the quality of gas in America. Any suggestions?
