Engine running rough and acceleration problems with Peugeot 301 petrol engine (2021) - Possible defect in the tank ventilation system?

Hello, I had a similar problem with my Peugeot 308, year 2019. Another model in the same house, the Peugeot 3008, also had similar symptoms. I have little experience with car repairs, but I solved the problem in my garage. On my car, the hoses were clogged, which cost around 175 euros. You could have this checked at your garage. To help you further, could you please give me more details about your vehicle? For example, mileage and whether the car often covers long distances. Hope that helps you!

Hi, thanks for your quick reply! My Peugeot has 38906 KM on it so far and I usually only drive it on short trips in the city. There was nothing unusual at the last inspection. I'll take your assumption about the clogged hoses to the garage, thanks for the tip!

Hey, thanks for the additional info! Yes, short distances could actually exacerbate the problem. You don't have as much opportunity to use the car's full power and blow through everything. My recommendation would actually be to take it to the garage. I had also driven the car for short distances and then got these problems. After the repair, I tried driving longer distances from time to time and since then the engine has run much more smoothly. I hope that the hose replacement will also have a positive effect for you. Feel free to give us an update on how the visit to the workshop went. Good luck and have a good ride!

Hello, thank you very much for your detailed answer and advice! The short distances make sense. I'll definitely take it up with the garage and have a thorough inspection done. Hopefully it's just a minor problem. I'll keep you posted as soon as I find out more. See you then and thanks again for your help!
