A vacuum leak can also make it idle high too. A hissing sound can be heard under the hood if thats the case. The hose that comes loose for me is the T connection behind the intake manifold that goes to the cruise control and the heater valve. If those are OK double check under the intake manifold for the connections to the little canister and metal lines that wrap around the block. and go to the injector regulatorI have an NA so Im not sure about the turbo.
Here is a cygnus link that shows better than I can explain.
