Hello I need your help. From now on, the Punto has had the same drop-off and engine stock. Early in the morning in cold condition quite normal, the engine control turned a bit hot. On the way home, the one stayed on and that came into the workshop. Cylinder 4 ignition drop-outs. Control unit defective, economic total damage. The Punto is in the garage, control unit is a ME7.3H4 from Bosch, which doesn’t break so quickly and is already protected against overvoltage. Ignition cables are relatively new from Beru and 100% ok. Spark plugs now come in after 20,000 km at short distance. The ignition coil pack is damaged, look at the picture, for 15 years there inside. I suspect that the one who makes the error, however, is the right coil for cylinders 2-3 damaged and not 1-4. I suspect that the evaluation and control of the ignition only goes to the coil, since no direct ignition coils on the candles are as well as today. Cold cords and has power starts after a while. Temperature sensor, if it is warm, nevertheless, it does not show a new possibility. And it has a new problem.
