Let me guess, you have a cold air intake? It's perfectly normal, what you hear is the Idle air control valve opening to bring up the idle for warm up mode. Normally the air filter and assembly muffles the sound down enough that you won't hear it.

LOL.......check the rubber intake tube from the air filter to the throttle body for a crack./hole or the metal tube on the back side being loose. Just a guess...but an educated one.
