Peugeot 308: Problem with throttle response during cold start
(Translated from German)
Summary of the thread
A 2009 Peugeot 308 with a 1.6L engine experiences delayed throttle response during cold starts after sitting for extended periods. The issue resolves after briefly revving the engine and does not occur on subsequent starts the same day. Potential causes include a dirty throttle body, which was cleaned, and possibly a malfunctioning mass airflow sensor. Cleaning the throttle body may resolve the issue, but further investigation into the mass airflow sensor is suggested if the problem persists.

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!
Thank you for the information, I will check this tomorrow and let you know if it helped.

I also cleaned the throttle valve; it was dirty. Now I'll wait and see what happens; so far, it's running.

Great to hear that you cleaned the throttle valve. If the issue persists, consider checking the mass airflow sensor (MAF) for any dirt or malfunction, as it can also affect engine performance during cold starts. Keep me updated on your progress, and feel free to ask if you have any further questions!
