1. Fuel pressure regulator: The fuel pressure regulator controls the amount of fuel that is sent to the engine. If the regulator is faulty, it can cause the engine to receive too much fuel, which can lead to flooding and dumping of gas.
2. Fuel injectors: The fuel injectors spray fuel into the engine's cylinders. If the injectors are clogged or damaged, they can cause the engine to run rich and dump gas.
3. Oxygen sensor: The oxygen sensor monitors the amount of oxygen in the exhaust gas. If the sensor is faulty, it can cause the engine to run rich and dump gas.
4. Mass air flow sensor: The mass air flow sensor measures the amount of air that enters the engine. If the sensor is faulty, it can cause the engine to run rich and dump gas.
5. Coolant temperature sensor: The coolant temperature sensor monitors the temperature of the engine coolant. If the sensor is faulty, it can cause the engine to run rich and dump gas.
6. PCV valve: The PCV valve allows air to circulate between the engine and the air intake. If the valve is stuck closed, it can cause the engine to build up pressure and dump gas.
7. EGR valve: The EGR valve allows exhaust gas to be recirculated back into the engine. If the valve is stuck open, it can cause the engine to run rich and dump gas.
If you are unable to identify the cause of the problem yourself, you should take your car to a qualified mechanic for diagnosis and repair.
