Toyota 4Runner intermittent stalling on hot days with gas smell after driving on Toyota 4Runner

Some Toyota 4Runner owners report experiencing intermittent stalling issues on hot days, often accompanied by a gas smell after driving. These problems may stem from various factors, including issues within the fuel system, such as a faulty fuel pump or clogged fuel filter, which can lead to stalling and gas odors. Additionally, problems in the air intake system, like a malfunctioning Mass Airflow (MAF) sensor, may also cause stalling and trigger the check engine light. Furthermore, faulty spark plugs or spark plug wires could contribute to these intermittent stalling episodes and the associated gas smell. To effectively address these concerns, owners are advised to have the fuel system, air intake system, and ignition system components inspected for malfunctions or damage. If the issues persist despite these checks, consulting a qualified technician for a thorough diagnosis and repair is recommended to ensure optimal performance of the Toyota 4Runner.
