Have a CEL on and don't honestly know much about volvos and was hoping you can explain which hose this is. I have one that looks like it's by the intake manifold and it has a good 1" gash in it. Second picture shows a hose(?) by the MAF and looks like it leads somewhere, but I can't find it whatsoever.


Any help would be appreciated, thanks.

 

Check all of your intake hoses, pipes and clamps - replace, tighten as nessesary. When you have stopped your intake air leaks, your lean condition will disappear . The vacuum line in picture 2 goes to the boost control solenoid located below the distributor. It's about 2 inches long with a wires plug in one end and 3 vacuum lines in the other. It lets the computer control the turbo boost pressure.

 

I got the intercooler hose taken care of, but the 2nd line in the diagram is kicking me in the butt... where to the boost control solenoid does it go? I see the three vacuum lines that go out, but I can't for the life of me figure out where it goes.

found this pic set googling "volvo 850 boost control solenoid"

 

It looks like it goes beneath the distributor caps? I'm really lost right now because I keep getting conflicting answers, is there a chance there's a vacuum line just deep down in the engine that I need to fish for?

 

yep, some of the vacuum lines are a pain to get at - some go down under the intake manifold to the PCV system and there is (are?) a line to the boost controller which is under some parts over on the #5 cyl side of the engine (as you noted - by the distributor) which may require some minor removals...
