84 starion vacuum issues

so I just bought Boosted88TSI 84 Starion and am trying to get it ready for 24 hours of lemons, am familiar with turbo cars, 1.8t VW and Audi V6 bi-turbo S4 but when I look into the engine bay of this Starion am feeling a little overwhelmed. there are a lot of missing vacuum lines which I believe to be the major cause of a rough idle and unable to idle, so I was wondering if anyone had a link to a vacuum line chart or any other lines for this car because I am going to end up running all new lines to start fresh, anyone that is local and knowledgeable with this car, Santa Cruz area, I will supply the beer if you are willing to stop by and lend your expertise.

rough idle can be causes by a lot of different things. Bad egr, stuck jet valves, dirty injectors and so on. Also check out the larger line that goes from the intake manifold to the brake booster. It splits off and goes to the abs module. these lines dry rot pretty bad and may be leaking but look fine. Does the car run okay?

the line that goes back around to the air cleaner is for barometric compensation. The solenoid on the firewall next to the map sensor switches every 30 seconds(I think) and samples atmosphere before the turbo. This line could be anywhere buts best to be in the air filter housing.

 

Do you have no MAS in your airbox?

Like Shift said, the line to the air filter housing isn't really a vacuum line. It just samples air pressure for altitude adjustment. I just left mine open at the solenoid and it works fine but I guess I am at some risk of dirt getting in.
