Hyundai i30: Jerking during acceleration despite new ignition coils

Hello everyone, I have a 2017 Hyundai i30 with a 1.0 T-GDI gasoline engine and 81,845 km mileage. I have the following problem: When accelerating hard, the car starts to jerk and the engine speed fluctuates. This problem only occurs when the tank is full, the engine is warm, and in the rev range between 2000-5000 rpm. The ignition coils and spark plugs have already been replaced and are new. Does anyone have an idea what the cause could be?

Check the fuel tank venting system for any blockages or malfunctions. A clogged vent can cause pressure issues when the tank is full, leading to jerking during acceleration. Let me know if this resolves the issue or if you need further assistance.
