what hoses you checking? best way to check for vaccum is carb. cleaner. start engine and spray everywhere on it, when you find a vaccum leka the idle will change usually increase.

to check for heater hoses, with a warm engine and gloves on, bend and feel each hose for moisture and cracks and visible leaks.
