Hello together, My 95 Volvo 850 (petrol with 144ps) makes fax times again. Problem is that it goes down while driving with the speed only extremely slowly. As a result, the actual braking effect when gasless rather converts to acceleration. At the gas train it can not lie (my first thought). After a little search with the mechanic of my trust, it turned out that the problem can be fixed with the idle control valve. In turn, I was thoroughly cleaned with brake cleaners. However, this did not solve the problem. Will I have a new old replacement installation and hope that it will be done with it. Does anyone have any other ideas about what it might be or experiences in the direction? Greetings Geiger
