Citor C3 1.1 sometimes goes out when accelerating

Moin together. I’ve recently had a Citroen C3 1.1 petrol engine with the following symptoms: When I start it it runs and stays on. If I give it short gas bursts it can be that it simply runs out. In addition, the engine runs on and for itself a bit unevenly. I also have the feeling that it runs well right after the start when it is cold but then starts to run unround within the first minute. Engine control lamp is off and even when reading out there is no error. But he doesn’t always go out. Sometimes he runs like a champ. And if you keep him on say we times 3000rpm then he also runs super round. When driving it is similar. Sometimes he runs great times he just goes out while giving gas. And if he runs out while driving then he also stays out, even if I don’t couple “except” I turn off the ignition briefly and again. Then he’s right back there. So domes, walk down and let come back nix if I don’t get first ignition As if he didn’t release any sparks otherwise. Camshaft sensor has already come new and falls away as a mistake. Except of course there is a cable break somewhere. As I said, I had the engine read out several times and there was never any error. Does anyone know this fault picture and can do something with it? Tool, multimeter and readout device are available. Here the data about the car: Citroen C3 1.1 First registration: 06.2002 Key No: 3001 788 F INN: VF7FCHFXC26062527
