Hi, everybody. I would be happy for your help again. I went on vacation today. After the first short coffee break, the engine was rumbling a bit at the first meters, but after that it was normal. Then it was over an alpine pass. At a construction site only one lane could be driven. At the start of the race the engine was rumbling at the red light and didn’t have the power to start. A two restarts went, but completely restless run and no power to start on the mountain. in half an hour, the engine started, but with a lot of gas it got better. He then escorted us up the mountain a few kilometers and then went back and we continued. At the next pass, this time in the middle of the construction site, the engine went downhill again. This time we just waited 15 minutes, tried again, gave a lot of gas and: continued. Two hours later we arrived in South Tyrol. The man from the breakdown service What do you think? Could it be the petrol pump? I haven’t changed it yet (more than 380 Tkm). Or can the relay 103 cause such symptoms? Or can it do something with the ignition? I would have had the spare gasoline pump with me. Whether it still works would be checked. I also have new relay in the car. What would you do? Thank you for all the hints already in advance!
