* Fuel pressure: If the fuel pressure is too low, the engine won't be able to get enough fuel to run properly. Check the fuel pressure regulator and fuel pump to make sure they are working properly.
* Airflow: If the airflow is restricted, the engine won't be able to get enough oxygen to burn the fuel. Check the air filter and throttle body to make sure they are clean and free of obstructions.
* Spark plugs: If the spark plugs are worn out or damaged, they won't be able to create a strong enough spark to ignite the fuel. Check the spark plugs and replace them if necessary.
* Fuel injectors: If the fuel injectors are clogged or damaged, they won't be able to deliver the right amount of fuel to the engine. Check the fuel injectors and clean or replace them if necessary.
* Oxygen sensor: If the oxygen sensor is not working properly, it won't be able to send the correct signal to the engine computer, which can cause the engine to run rich or lean. Check the oxygen sensor and replace it if necessary.
If you have checked all of these things and your car is still running but cutting off when you hit the gas pedal, you should take it to a qualified mechanic for further diagnosis.
