Why does my engine sputter when I give it gas?
One of the most common causes of a sputtering engine is an issue with the vehicle’s fuel system—the filter, pump, and injectors. Since the fuel filter, pump, and injectors work together as part of one interconnected system, dirt and debris need only clog one part to cause the others to fail.

- Check the condition of the fuel injectors.
- Turn on the engine and check the fuel spray pattern on the throttle body injector if your particular vehicle has one.

Why does my engine sputter on acceleration?
Engine misfiring or stumbling is a sign that your car is not getting enough power from the engine during acceleration. A car sputters when accelerating due to the fact air and fuel is not being properly mixed , therefore, forcing the car to run on unburned fuel. Another reason could be a weak transmission system that misfires when the engine experiences an extra load.
