Breath that smells like rotten eggs is often caused by the presence of hydrogen sulfide gas, which can result from certain bacteria in the mouth or throat breaking down food particles. Conditions such as poor oral hygiene, gum disease, or dry mouth can exacerbate this odor. Additionally, dietary choices, such as consuming sulfur-rich foods like garlic and onions, can contribute to this unpleasant smell. If the problem persists, it may be wise to consult a healthcare professional for further evaluation.

Exhaust fumes can enter a vehicle due to several factors, including leaks in the exhaust system, such as damaged pipes or a faulty muffler. Additionally, a malfunctioning cabin air filter or a blocked ventilation system can allow outside air, including exhaust gases, to enter the cabin. Poorly sealed windows and doors, as well as the vehicle's design, can also contribute to this issue, especially during acceleration or when driving in reverse. Regular maintenance and inspections can help prevent these problems.

A gas smell and difficulty starting in your 1990 Toyota 4Runner could indicate a fuel leak, a failing fuel pump, or a clogged fuel filter.

Consider having a professional mechanic inspect the system to identify and resolve the problem.

A car may smell like rotten eggs due to a problem with the catalytic converter, which is responsible for reducing harmful emissions. When the converter is malfunctioning, it can fail to properly convert hydrogen sulfide gas—found in fuel—into odorless compounds, resulting in a sulfurous smell. Additionally, a build-up of sulfur in the fuel or issues with the fuel system can also contribute to this odor. It's advisable to have the vehicle checked by a mechanic if this smell is detected.
