Why Is My Car Sputtering When Accelerating?

The most common cause of a car sputtering when accelerating is that you’re using too much throttle. If your car starts to sputter, ease off the gas and then try accelerating again. If the problem persists, check your engine for any loose or dirty parts that can cause vibrations or other issues.

If you’re still having trouble, you could have a problem with your fuel system, which could be due to a dirty fuel filter or faulty fuel pump. You should also check the air filter and make sure it’s not clogged with dirt or debris.

Check the engine

Check the engine. If you have a large amount of corrosion buildup on the engine or in the fuel system, this can create a build-up of carbon, which will cause the vehicle to sputter when accelerating. You can clean this off with a wire brush or an old toothbrush.

Check the air filter

If your car is sputtering when accelerating, it could be because of an air filter issue. The air filter serves to keep dust and debris out of your engine, which can cause damage over time.

If you notice that your car is sputtering when accelerating, check the air filter first. If it’s dirty or clogged, get a new one and install it as soon as possible. This should solve the problem.

Check the battery

The first thing you should do is check the battery itself. If it’s cracked or leaking fluid, it needs to be replaced as soon as possible. If it’s fine, then you can try charging your battery and see if that fixes the problem. If charging doesn’t work, then you’ll probably want to take your car into a mechanic for a more thorough inspection.

Check the transmission

The transmission is what’s responsible for getting your car from point A to point B. It’s also responsible for making sure that your car doesn’t stall out or bog down when trying to accelerate.

If you feel like your car is struggling with acceleration, but you don’t see any major issues with the engine, there’s a good chance that your transmission needs servicing or repair.

One of the best ways to tell if your transmission needs servicing or repair is by listening closely to how your car sounds when accelerating. If you hear a loud whining sound coming from underneath the hood, then it’s likely that you have some sort of problem with your transmission.

Check the pump

The pump may have a clogged filter or a leaky gasket. You can check the filter by removing it from the bottom of the fuel tank and running your finger over it; if you feel any dirt or debris, replace it. If there is no debris on the filter but your vehicle still sputters when accelerating, you may have a leak in your fuel line or tank that needs to be repaired.

Check the injector

Injectors are responsible for delivering the fuel mixture to the engine’s cylinders. If they are clogged or leaking, they will not be able to deliver enough fuel to keep your engine running at its best. This can cause a sputtering problem when you’re trying to accelerate quickly.


When your car sputters when accelerating, it may be due to a number of causes. The most common cause is a faulty spark plug wire. Other causes could include a faulty fuel injector or a clogged air filter. If you notice any of these symptoms, it’s important to get your vehicle checked out by a professional mechanic as soon as possible.
