Hello, I’m anything but an expert, I bought the car only 3 months ago and still learn, please don’t deal so hard with me! So I had the problem with my 850er already several times during the ride, that the speed suddenly goes to 0 and the engine no longer takes any gas. That has always occurred only briefly, only 1-3 seconds, until the speed accelerates again and again gas arrives… Yesterday he did not catch himself and I I then turned off the engine and couldn’t start the car after that. Only after about 10 minutes I was able to start again and then he drove again normally…. I think the error has only occurred until now when I drove in the fifth gear and faster than 80km/h… But am not 100% sure. Does anyone know what this might be about here? In the forum I found out that there are probably problems with the throttle flap. nn… However, it was described that the speed suddenly goes up in idle… That’s never happened to me before. And I just wanted to make my mistakes blink out, but I had to find out that there is nothing in my 855er where, according to YouTube video (https://www.youtube.com/watch?v=tbYwpSiXx4g ) is the flashbox on the 850er. Is there really only the 850er and not the combo?? The exact model name is: VOLVO 855-552 GLT 2.5-PK – 125 kW / 170 PS(1996)
