Unhappy Seafoam problem HELP!!!!! PLEASE! (Humming noise from intake)

I just Seafoamed my motor (d16y8) 159,000km's 1996 Civic SI
stock motor. i also cleaned the throttle body. Now I am hearing a humming noise through my intake sounds like a vibration but NOT! Because i made sure the intake was tight, nothing looses, nothing touching against it, and even took my intake pipe off!!

The sound is coming fromt the throttle body at idle. After i seafoamed the motor i made sure vacuum line was tight and everything else. As soon as i started it up, i heard the noise, knowing my car as good as I do I know it's not normal at all. I did take the car for a long high speed highway drive hoping it would clear the noise, it didn't

Any help would be much appreciated guys thanks, Please Please Please somebody help me!!

i don't think feeding seafoam thru the vacuum line cleans the throttle body. i've never heard of this problem before? i don't see how the seafoam will reach the TB when the air is getting sucked in from there and go back into your intake manifold.

Are you sure its a humming or more like a sucking noise like the sound of sucking air through a straw.

Seafoam wasn't meant for throttle body, did you physically put it in via the throttle plate?
