Hello, I’m new here and I’m not very familiar with engine technology either. I have a problem with my Lupo, he has now about 170000 km on it and has always run flawlessly up to now. Recently, a power drop of the car occurs at very irregular intervals after more or less driven kilometers. He drives hardly more 120Kmh on straight routes and he normally drives a lot faster. He starts to jerk down below 2000U/m and also has problems with the restart, the r engine sounds different too. It’s funny if I keep standing and the engine off and off again everything is OK again. Before I bring it to the workshop I wanted to be smart here, then if a friend could fix it. I found nothing similar here. Thank you in advance, Greeting Alex
