Is your engine idling roughly? There is a good chance this is related to a direct-injection petrol engine. Modern engines are now almost all direct-injection engines due to increasingly strict European emission requirements designed to reduce CO2 emissions. However, this development can also cause certain engine problems, such as an engine that does not idle properly or idles unevenly.
Cause of an engine that does not idle properly
One of the main causes of rough idling in direct-injection petrol engines is contamination on the intake and exhaust valves. This contamination can cause several engine problems.
If your car idles roughly, what can you do yourself? The cheapest and easiest solution is to add a fuel additive. First, we recommend cleaning the entire fuel system with Lindemann Service Cleaner Benzine or Diesel. This product is one of the best fuel system cleaners on the market. Once the fuel system has been cleaned, the problem may be resolved.
To keep your engine’s fuel system clean, we recommend using Lindemann Fuel System Cleaner. One 400 ml bottle of Lindemann FSC is suitable for 400 litres of petrol, which equals around 8 to 10 refuels. This additive is suitable for both preventive and corrective use.
Our advice: if your car or engine is idling unevenly, first clean the fuel system with Lindemann Service Cleaner Benzine and then keep it clean with Fuel System Cleaner.
