Hi, everybody, I turned off my Volvo S40 1.8i BJ2001 last week. When I wanted to start again, he gave gas all the time when I was idle. I then stuck off the air mass meter and then he stopped it and had an increased speed of about 1200 revolutions. So I thought it was because of it and built a new one. After that the problem had not solved. throttle valve cleaned up. Intake checked if it was where Falsc hluft pulls (negative). Still the same thing. But if I drive now then he has, if I drive a slight slope like light dropouts and has hardly any power. He then jerks so lightly. Furthermore he had a round speed and a also too low speed in warm condition (500-600). And he also turned up at the cold start up to 2000 revolutions and then fell down to 1500. Maybe someone else has an idea. I would still have an option. Greetings
