4 Causes of the Engine Stalling at Low RPM

4 Causes of the Engine Stalling at Low RPM – The cause of a car stalling at low RPM is something that car owners rarely know about. Even when the engine stutters at low RPM, some car owners don’t feel it. They consider it normal and there is no problem with the car engine. Though this is an engine problem that can be serious. Knowing the cause of this problem makes us understand why the car can stutter at low RPM.

So, what causes the car to stall at low RPM? Let’s see the full review below so you can get over it immediately!

4 Causes of the Engine Stalling at Low RPM

Experiencing a stalled car while driving is not comfortable. In order to avoid this, here are some things that can cause the car to stutter at low RPM.

1. Spark Plug Starts to Damage

Causes of the Engine Stalling at Low RPM
A spark plug that causes the engine to stall at low RPM does not mean the spark plug is faulty. If we let it, then this will be a serious problem until the engine knocking occurs.

The first cause comes from the problem of car spark plugs. This is one of the most common causes of car stuttering at low RPM. Car spark plugs that are starting to fail but can still burn most of the fuel and air in the combustion chamber. However, the spark plugs can barely burn completely the fuel and air in the combustion chamber, especially at low engine RPM.

You need to check your car’s spark plugs regularly. The use of spark plugs that have entered the replacement age or are not up to standard can actually cause the car engine to feel sluggish when we start to step on the gas pedal for the first time.

You should not force spark plugs that are no longer fit to use. If you find a damaged spark plug problem, immediately come to the repair shop to replace it. Thankfully you can replace the spark plugs yourself. For self-injection car users, you can use resistor spark plugs that are suitable for the injection system.

You should understand that all components in a car must meet standards. If not, then the car’s performance will not be optimal. Therefore, make sure to always buy spark plugs according to the standard recommended by the manufacturer. Or if you are worried about the wrong spark plug, you can come to your car’s authorized repair shop.

2. Fuel Not According to Factory Recommendations

New engines usually require an exact octane number. This is not without reason because the octane number determines how complete combustion is in the combustion chamber when the engine is running. Especially this for engines when the RPM is low.

The second problem that can cause the engine to stutter at low RPM is a fuel problem. Fuel that is not as recommended, such as low-quality and dirty fuel can cause this problem. The reason is because it can cause the combustion process is not perfect. This is what ultimately makes the condition of the car engine stutter, especially at low RPM.

If the problem comes from fuel, then the engine stalls when the engine is cold at low RPM. When the engine is hot, usually there is no stutter in the engine. Even a normal engine at low RPM though. Why is that?

This is because when the engine is cold, combustion occurs only relying on compression and spark plugs. When the fuel is not good, this will not occur complete combustion. When the engine is hot, the combustion chamber will be hot before the compression stroke occurs. After compression occurs, the fuel and air are in a state that is really ready for combustion. Thus, the combustion becomes complete and there is no more stutter in the engine, both low RPM and high RPM.

3. Dirty and Damaged Fuel Filter

The condition of a very dirty gasoline filter like this can cause the engine to choke, especially at low RPM. If it is very dirty, even the car engine will limp at idle or acceleration.

In addition to running out of fuel or low quality fuel, a clogged car engine can also be due to a dirty or damaged fuel filter. This fuel filter functions as a filter so that the flow of fuel entering the engine combustion chamber is free from dirt and dust. Fuel that is problematic or not clean will make the combustion process less than optimal. This less than optimal combustion process makes the car stagnate when gassed at a low RPM.

Meanwhile, the fuel filter will also get dirty over time. Even if the fuel is of high quality, the filter will still get dirty at different times. The use of good quality fuel will extend the life of the fuel filter from dirty and even damage. Again, the filter will still be dirty and damaged over a period of time.

To overcome this, the first step you have to do is to check the fuel filter. Most cars on the market today have two types of fuel filters. Perform inspection and cleaning on both filters. Be sure to drain the fuel first before cleaning the filter.

Any type of car, you should do regular cleaning or replacement of the fuel filter. Another precaution is not to mix the fuel as it can corrode the car’s tank. You can do it yourself or take it to a repair shop to clean or replace it.

4. Car Engine Overheating

The last Causes of the Engine Stalling at Low RPM is overheat engine. Engine temperature can also be the cause of the car stuttering at low RPM. An overheated car engine can reduce the speed of the car. When the gas pedal is stepped on, the engine speed will falter as if it is not powered.

High engine temperatures can be due to radiator water that has run out or even runs out. This is because the radiator water has a function as a coolant to maintain a stable engine temperature.

If this problem occurs, you can solve it by refilling the radiator water. Make sure to always use radiator water that suits the needs of the engine. Having the right radiator water can keep the engine temperature stable.

That is why it is important to carry out regular maintenance. An engine that rarely gets the recommended maintenance can increase technical problems, such as a stalled car. You should adhere to a regular service schedule.

So those are some other causes that can make the car stagnate when gassed at low RPM. To fix this, you can immediately take the car to your subscription repair shop.
