6 Causes of Cars Stalling While Driving & Their Solutions

The causes of a car stuttering while driving are due to many factors. Therefore, understanding the causes and how to address these issues is essential. Because if the cause is trivial, you can resolve the issue independently without directly contacting the workshop.

However, if the condition requires expert handling, you can take it to the workshop. Rather than being curious, here we will detail how to address a stuttering car while driving and what the causes are.

Causes of a Car Stuttering While Driving

Here are some factors that cause a car to stutter while driving, including:

1. Fuel is Almost Empty and Not According to Specifications

The main cause of a car stuttering while driving is usually due to fuel that is almost empty. As a result, the engine cannot operate because the fuel supply is not optimal.

In addition, another cause is that the fuel used does not meet the specifications of the car's engine, such as using fuel with a low octane rating.

2. Spark Plug is Damaged or Poor Quality

The spark plug is a component that plays a role in igniting the fuel during the engine's combustion process. Therefore, if the spark plug has been used for too long, its condition will deteriorate and wear out. This is also what causes the car to stutter when the engine is hot.

Damage to the spark plug or using a spark plug of poor quality that does not meet standards can cause suboptimal engine combustion performance due to weak sparks produced.

3. Sensor System Issues or Damage

The ECU (Electronic Control Unit) in the car functions as a determiner of fuel injection duration (determining the right time to provide the air-fuel mixture or when to supply the right amount of fuel to the engine).

This can cause issues or damage to the sensor system of this component. Consequently, the fuel supply becomes chaotic because the data signals produced are inaccurate, which can lead to the car stuttering.

4. Issues in the Fuel System

Why does the car stutter when accelerated? The cause is usually due to problems in the fuel system. For example, issues in the pump filter, carburetor, injector, and other components that are dirty and clogged can also cause the car to stutter.

5. Injection System Has Air Ingress

Just like humans, the injection system can also suffer from "air ingress." Fuel injection channels that have air or gas can cause the car to stutter while being driven.

This is due to the presence of air bubbles in the injection system, leading to instability in fuel pressure.

6. Radiator Water is Empty

Empty radiator water can cause the car to overheat and stutter while being driven.

How to Address a Car Stuttering While Driving

What should be done if the car engine stutters? Here are some ways to address your car stuttering while driving, including:

Use fuel that meets the engine specifications or high octane. Also, always monitor the fuel tank, ensuring it is always full or not exceeding the red filling limit.
Always routinely check the condition of the spark plugs and ignition system. If the spark plugs are damaged or problematic, replace them immediately with quality new spark plugs.
Immediately take the car to the workshop when the ECU sensor system has issues.
Regularly maintain the injection engine combustion system, either by yourself or by taking it to the nearest official workshop.
Always check the condition of the radiator water; if it is low or empty, refill it with new radiator water.
Tune up the car. Perform a tune-up process if the previous methods do not improve the car's condition and it continues to stutter.

Thus, the information regarding the 6 causes of a car stuttering while driving and how to address it. If the above methods do not yield results, you can take it to the nearest official workshop or Daihatsu dealer for proper and maximum handling, such as replacing problematic car components.
