Hello dear friends, my vehicle 307 1.6 xt 1 month ago, the ignition coil had failed. Before the malfunction, the engine was working normally when the sound gave a gas. But it failed, I changed it. it still gives the same muffled sound. As soon as he gases, the vehicle will drown. When I go on the road, I get the same second gear when I accelerate normally in other gears, there is no hoarse voice, but when I suddenly accelerate, I hear that voice. A muffled sound sounds as if the vehicle is wearing an exaggerated exhaust. I wonder why there is such a sound.
