Megane II Convertible 1.6 with 113 hp No 3333 034 Built 2004 simply goes off during the ride.

Hello, My Renault Megane II Cabrio Bj 2004 goes out during the ride. Currently it has 146T km. I notice that just while parking, or slowly rolling towards a traffic light. The fault diagnosis shows no errors and the throttle flap I cleaned. After cleaning the engine ran equally stable and took the gas very well. But short time later it started again. At the traffic light it just went out – during the ride he then very jerked and I had to give a lot of gas. After that he caught himself again after 2-3 min, but then went off again. In the cold start everything runs normal. When I drive through the city and then turn off the car to start again after a certain time, he makes after a few minutes of traffic lights etc problems. If then I stay on the gas constantly during the drive, he starts to jerk and the car makes “gas strokes” Have tried to order a idle control, but have seen that the in the complete Dros I had changed ignition coils 2 years ago – but he would have to show them in the FS? Tank is full – and sometimes it smells a bit like gasoline. could you help me? Greetings
