* Clogged or dirty fuel injectors can cause the mixture to be too rich, leading to a strong fuel smell.
Faulty Oxygen Sensor:
* A damaged oxygen sensor can provide incorrect information to the engine control unit (ECU), resulting in improper fuel-to-air mixture.
Exhaust System Problems:
* A leaking or damaged exhaust system can allow unburned fuel vapors to escape, causing a gas smell in the car.
Catalytic Converter Issues:
* A faulty catalytic converter can fail to convert harmful exhaust emissions, resulting in a strong gas odor.
EVAP System Malfunction:
* The evaporative emission (EVAP) system is responsible for containing fuel vapors. A malfunctioning EVAP system can cause fuel smell to enter the cabin.
Engine Coolant Temperature (ECT) Sensor Problems:
* A faulty ECT sensor can provide incorrect temperature readings, leading to an improper fuel-to-air mixture.
Mass Air Flow (MAF) Sensor Issues:
* A damaged MAF sensor can provide incorrect air flow readings, affecting the proper air-to-fuel ratio.
Vacuum Leaks:
* Vacuum leaks can cause the engine to run rich, resulting in a gas odor.
