Do you have a propane torch? You can run an unlit propane torch with the valve cracked open over the suspected hoses while your engine idles. If you pass it over a hose and it idles up and take the torch away and it idles down - the replace that hose. The propane going in the system will correct the Air Fuel ratio causing it to idle up.
