When your vehicle makes noises and odd jerking movements, there are possible major issues occurring. These problems often stem from the exhaust or fuel system. The exhaust system moves all engine gases starting from the cylinder head all the way to exiting the exhaust pipe. Additionally, the fuel system is what stores and supplies fuel to the engine, allowing your vehicle to move. Asking why is my car sputtering when I step on the gas pedal indicates a problem that Kernersville Auto Center handles.
Exhaust System Problems that Cause Jerking and Shaking
- Worn out Seals or Gaskets – These numerous seals and gaskets are all along the exhaust system. However, they wear out over time. As a result, this causes exhaust gas leaks. Leaks will cause shaking and sputtering when accelerating.
- Catalytic Converter Problems – An issue with this car part is sometimes more obvious because it has a rotten egg smell. This type of problem will lead to larger issues if not resolved. Eventually, your vehicle will not start because of a blocked catalytic converter.
- Exhaust Manifold Leak – The exhaust manifold traditionally funnels spent exhaust gas from the engine. A cracked manifold creates a leak that will cause a vehicle to sputter or run jerky when you accelerate.
- O2 (Oxygen) Sensor Failures – Vehicles now have sensors and computer components that help it run properly. The O2 sensor measures how rich the exhaust gases are as they leave a vehicles combustion chamber. When an O2 sensor no longer works, it will not send the proper information to the vehicle’s computer. In turn, the computer does not send the correct amount of fuel to the engine.
Fuel System Problems that Cause Jerking and Shaking
- Dirty or Failing Spark Plugs – The job of a spark plug is to ignite the fuel in the combustion chamber. Therefore, if one is dirty or faulty, your engine will struggle to start and sputter when you hit the gas.
- Fuel Injectors That Are Dirty – Other critical parts in your vehicle for starting are the fuel injectors. They spray fuel into the cylinders. A clogged fuel injector nozzle causes a car engine to shake and struggle to accelerate.
- A Dirty Mass Airflow Sensor – This sensor will also lead to a shaking engine. It measures the amount of air that is entering the fuel injection system. If a mass airflow sensor is dirty, it sends the wrong information to the vehicle’s computer. Thus, the computer will deliver the incorrect amount of fuel to the combustion chamber.
- Old Fuel Filter – Also, if you do not regularly have your fuel filter changed, it will become less efficient. It keeps rust and dirt particles out of your fuel system. When it cannot properly do its job, it causes failure of the fuel pump and fuel injectors.
