The engine does not run smoothly - that could be the reason

If you notice that your engine is not running smoothly while driving or at a standstill, there may be many reasons for this. We have summarized the most common causes and what you can then do in our home article.

The engine does not run smoothly - that could be the reason

Not every problem with the engine has to be directly related to major damage; small causes are often responsible for the problems. Read here about the most common reasons for an engine that is not running smoothly:

  • Spark plug: In a gasoline engine, it can primarily be due to a defective spark plug that the engine is not running properly. Then the spark will no longer be formed correctly and the engine will not be able to achieve full power. You should replace a spark plug every 30,000 to 40,000 kilometers. The exchange can be done quickly in a workshop and does not cost you a lot.
  • Injection nozzles: The injection nozzles can also be defective or clogged. If this is the case, the fuel can no longer be injected into the cylinders of the engine. The result is an irregularly running engine and significantly higher fuel consumption. You can also see dark smoke on the exhaust. If all signs are correct, have the nozzles cleaned or replaced.
  • Ignition cable: Another cause of the engine running irregularly can be a defective ignition cable. The ignition cable conducts the voltage to the spark plug. Without this voltage, the spark plug cannot work and there is no spark. The cable can be broken or just loosened. A marten can also have caused the damage to the ignition cable.
  • Fuel filter: So that your engine is supplied with clean fuel, dirt in the tank is separated in the fuel filter of your vehicle. The longer it has been since you last changed the fuel filter, the more likely it is that the filter is clogged. If this is the case with you, not enough fuel can get to the engine and the engine runs unevenly. Have the filter checked in a workshop.
  • Air: A problem that is easy to solve is air in the system. The accumulated air ensures that the fuel cannot reach the engine in a constant amount, which results in a jerky or uneven engine. The air can be released from the system through a special hose in a workshop.
  • Note: There are many other reasons that could be responsible for the problems. To avoid damaging your engine too much, you should always go to a workshop as soon as you first notice the problem. Repairs are often much cheaper if a fault has just occurred.
