Moin dear community, I woke up my Emil (W123 with OM 617) from hibernation this weekend. Of course he wintered in the garage with battery maintenance equipment for the battery. Tank is brimming full. He only jumped after the second start attempt and then ran terribly unevenly until he was out of the garage. Feeled not all cylinders ran. After that he ran in the standing gas after about 10 seconds round. I could not make longer trips (bold season marks…), wanted a Is this probably just the spark plug or a spark plug plug? Or can there be any “greater” threat? Perhaps an information about the car: W123 300 D, BJ 1980, km stand about 16,000 original. For hints (or only calming down 😉 ) I am grateful. Many greetings
