Hello together! I hope you can help me with my problem a little bit… Here’s my suffering story: On Saturday we installed a new windshield wiper engine on the Brava meienr friend. Everything wonderful! After a small splash trip came then but suddenly flammable oscillators up to the complete strike of a cylinder. Since the spark plugs were already a little older I bought the “good” also 4 new ones and see since he ran again perfectly. Sunday: the car was Monday: During my girlfriend’s daily shopping tour, she went on a complete strike of the 3rd cylinder (about 1km after leaving). She is then to the ATU *rolleyes* where she was not helped much more. These tapped on the ignition coil, which in my opinion cannot be. It is an ignition spark on every spark plug. However, which is not quite in order: If you pull off the 1st cable (from the left): engine stutters extremely and even stronger than if it is only on 3 cylinders. n runs you pull off the 2nd cable (from the left): engine stutters extremely and even stronger than if it runs only on 3 cylinders You pull off the 3rd cable (from the left): engine stutters…but not worse than before. So it has to be on the 3rd cylinder. If you pull off the 4th cable (from the left): engine stutters extremely and even stronger than if it runs only on 3 cylinders What else can it be? –Zündkerzen new and dry –Zündfunke is everywhere — and why was it after 4 new spark plugs for 1-2 hours ok and then the same again? PS: In the Tacho unit a red symbol sporadically shines on that looks like an injection nozzle. I ask for your help! Thanks already in advance!
