Best way is definetely a smoke test that a shop can perform. But for you on your own it can be attempted by spraying around the intake hoses, faccum lines, throttle body gasket and the upper and lower intake manifold gasket with starter fluid or carb cleaner. The area when sprayed that changes idle is where the leak is
