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.

What causes a car to sputter and shut off?
Spark Plugs
The spark plugs are an important part of your engine's combustion. They ignite the air and gas mixture in the combustion chamber to fire up the engine and keep it running. Dirty, old, worn, or misplaced spark plugs can cause your engine to misfire – sputter – and even stall if the plugs are really bad.
What causes exhaust to sputter?
A leak in the exhaust manifold can cause the engine to sputter because gases are leaking. ... A worn seal or gasket in the exhaust system can cause leaks and damaged the exhaust manifold. A failing catalytic converter can cause sputtering as well as the smell of rotten eggs.
Does a bad fuel filter cause sputtering?
Poor Engine Performance
Under heavy loads, a clogged fuel filter may cause the engine to randomly hesitate, surge or sputter. This tends to be more prominent when accelerating, especially up a steep incline.
Why is my car stuttering when I accelerate?
An acceleration problem is usually the result of insufficient fuel, air, or spark during the combustion process. Worn-out spark plugs or the electrical cables attached to them are one of the most common causes of cars stuttering.
Why is my car chugging when I accelerate?
Dirty Fuel Injectors
Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky. The dirty injector leads to your car losing power when you attempt to accelerate while at a stop and when you try to drive at a consistent speed. This is the result of an engine misfire.
What is bucking in a car?
In most cases when you apply pressure to the accelerator pedal, the engine slowly revs up and when in gear accelerates forward. ... When this occurs, it sometimes creates a hesitation in the application of the throttle or a "bucking" sensation.
Why does car sputter idle?
A faulty mass airflow sensor or oxygen sensor could be incorrectly calculating the air/fuel mixture. Dirty or clogged fuel injectors causing fuel puddling instead of atomization can cause a stumble at idle. Low fuel volume could also be an issue or a faulty engine computer if the issue happens even on a cold startup.
How do you know your fuel pump is going out?
If you notice a whining noise coming from the location of your fuel tank, the fuel pump is probably beginning to fail. If you hear whining, the fuel pump may be bad, you're running low on gas, or there are contaminants in the tank.
Where are fuel injectors located?
Fuel injectors are located in the intake manifold and spray fuel through a tiny nozzle. The fuel injector uses a special nozzle to spray the fuel as mist, instead of a strong jet stream.
