Hello dear ones! my good Hyundai Accent I 1.3 Bj 97 is fresh over the TÜV and that without defects However, it comes from 3000 u/min only sluggish for a few days. Up the mountain I hardly get to the 4000 ran in the fourth gear. Underneath it pulls as well as otherwise. Ignition error is excluded, the air filter and the candles are new, the ignition cables changed one and a half years ago. I have nowhere found a crack or similar for foreign air. Candle picture is clean, hole in the piston is therefore probably out It runs round and actually also at higher speed, but it feels like I suddenly have a trailer on it over 3000 u/min. The engine also gets louder, similar to a mopped where you can use Choke in it, coldly run the tap. Head seal, timing belts, turning rollers and new valves 1.Cylinders I did not even replace two years ago since about 40,000 km completely without problems. I was looking for compression, but the uniformly used power picture up to 3000 turned me away from the idea, especially since the engine runs reasonably round, also keeps up with speed and stability. Does anyone have any idea what the hell that could be?! I learned lubricating nipples years ago, but after the lesson stopped, welder learned and never worked as a car driver. A thousand thanks, PackerPunch
