A sputtering sound coming from your car’s engine is rarely a good sign.  But it can mean a variety of things. And some issues are far more easily fixed than others. So, why might your car engine be sputtering? And what can you do about it?

Five Reasons Why Your Car Engine Might be Sputtering

Fuel system error

Fuel system errors are probably the most common reason for cars to experience sputtering. If fuel is not flowing efficiently between the fuel tank and the fuel injectors, the car will struggle to run smoothly. The fuel system is really closely interconnected. So, engine failure is a real possibility if you leave problems unchecked. So, if your can begins sputtering, even just once or twice, it’s a good idea to investigate the fuel filters, fuel pump, and fuel injectors. But first, check your fuel gauge, and make sure that you actually have fuel in your tank!

Spark plugs need replacing

Your car’s spark plugs are a small but integral part of its transmission. Without them, the fuel and the air within your engine could not combust, and your vehicle would not be able to start. There are various signs that may alert you to the fact that your spark plugs are failing. And sputtering is most definitely one of them. So, if you notice any problems, you should replace them as soon as possible. If you don’t, you may be left high and dry.

Catalytic converter issues

The role of your vehicle’s catalytic converter is to convert harmful gases, such as carbon monoxide, hydrocarbons, and hydrogen monoxide, into safer, inactive gases. If your catalytic converter is not properly functioning, it will be unable to safely process the gases produced by the car’s engine. This can lead to a range of performance problems – some dangerous, including the build up of toxins in the car’s cabin – such as engine sputter.

Problems with the airflow sensor

A vehicle’s airflow sensor monitors the air involved its fuel injection process. Ensuring that the vehicle has exactly the right amount of air to perform efficiently. If the sensor is dirty or damaged, it cannot function properly. Impacting engine performance, and producing sputtering.

A leaky or blocked exhaust system

If your car’s exhaust system in faulty, it will exhibit similar performance issues as when the catalytic converter is struggling. If the emissions produced by your engine cannot be properly processed, it will influence the way that the air flows around the car. This, in turn, will impact the way in which fuel is passed through the engine. Making the engine sputter.

If your car engine sputters when you drive, take it as a warning sign. And get your car serviced. Because, while most of the problems that cause sputtering can be fixed relatively easily if dealt with swiftly, if left they can all develop into much greater and much more expensive issues.
