Renault Megane Cabrio 92T Km, built in 2004 113hp 1,6 Hi! About 2 months ago the Renault started in the stand to Ruckeln. According to FS analysis it was the ignition coils. In the meantime I had all 4 replaced in the workshop. New spark plugs are also installed. Now after my holiday it starts to jerk again in the stand. It sounds like a trecker, but it is not so crazily that it is just before the go out. The speed fluctuates slightly, but you notice it. What can this be about now? n has never driven Renault before, so I don’t know much about the typical problems with the model. could it be due to the MAP sensor (suction tube pressure sensor)? It wouldn’t be difficult to replace it.
