Hello, have 2 problems. But in advance I have to say that I-where is on the bend i-what leaks or hole ka… that it might be related to it. I have a car gas system inside of BRC First problem when I run the car with petrol I have the problem that the engine runs strangely, no continuous motor noise but always with a small pause here the video: YouTube When I drive with gas I don’t have the problem. Second problem at low speeds in the S tand, now with the video it was strange that the one jumped again to the normal speed of 800 rpm from one moment to the other. But from 1 min in the video it is almost always so that the speeds are at 300 – 400 rpm. here video: YouTube that is also always so when I am standing at the ampel o.ä. And yes since I drive with gas I had empty petrol tank, since I have once filled for 10€ petrol approx. 8 liters, then drove the tank empty and thus only 56km, that is doc H not normal?
