Peugeot 308: Problem with throttle response during cold start

Hello everyone, I have a 2009 Peugeot 308 with a 1.6L 16V 120 HP VTI gasoline engine and 195,000 km on the odometer. I have the following problem: If my car stands for a longer period, for example 2 days, and I start the engine, it starts immediately and without problems, but when I start driving, it takes about 5-6 seconds for the gas to be accepted properly. If I briefly rev the engine while standing still, it runs without problems afterwards. This problem only occurs on a cold start, regardless of whether it is warm or cold weather. If I start the engine again later on the same day, even after several hours, the problem does not occur. There are no fault codes stored, and the spark plugs and fuel filter are new. The idle speed at a traffic light is also absolutely stable and quiet. What could be the cause of this problem?

Check the throttle body for any carbon buildup or dirt, as this can affect airflow and cause hesitation during cold starts. Cleaning the throttle body might resolve the issue. Let me know if this helps or if you have any further questions!
