Hello, everyone. I have a Renault 19, 1.6, model 2000 and it occasionally happens that, when accelerating slowly, the engine does not respond properly; it accelerates and decelerates continuously as if fuel was not reaching correctly. However, if I accelerate it deeply, there is no failure at all. The check light remains turned on permanently. At idle speed, the car has got a discontinuous power cut. I've already changed: oxygen sensor, distributor cap, wires, spark plugs and the steering wheel sensor. When scanning the vehicle, no failure is indicated. What might be wrong? Rotor? Coil? Could you help me, please?

Hello, I have a R19 engine 1.8 and my problem is that when driving, at high or low speed, the engine suddenly cuts sharply, and immediately then continues working properly. It seems as if it were an electric failure because the cut is absolutely dry. I've changed the module, coil, wires, spark plugs, but everything remained the same way. Has this ever happened to anyone? Could you please help me? Thank you very much.
