Vacuum hosing for 1990 Volvo 740 GL

[Rafael]

Dear friend, I have a problem with my Volvo because it stalls at minimum. I had a not so good mechanic look at it and was told that there was an air intake at the intake manifold. i bought and changed the gasket and the problem is still there. But I also saw that there were several hosings that were not attached to anything. I calle dthe mechanic and he never answered. So now I have these tubings and I don´t know where they go. Couls I get a detailed schematic or picture where I can see what I need? Thank you very much. here in my city of Caracas I cannot find any mechanic that has experience with Volvos because in Venezuela there must be only about 20 in circulation. My Volvo was given to me as a present from my brother in law. The car has only 95000 miles and its brand new practically and I would like to keep it running in tip top shape because I love the car. Thank you very much.
