Vacuum Leak at TB

I can hear a constant sucking of air sound coming from right around my throttle body, I couldn't pinpoint it from the 10 seconds that I tried to figure it out. But I thought I remembered something about a vacuum leak problem at the TB being common?? I've had this problem for a while, but i've ignored it because when I punch the gas and let off, it kind of sounds like a small quieter blow-off valve. Again any help appreciated...trying to get this thing ready to sell!

Could be your idle screw or whatever they are called. I believe there is a cheap rubber washer that goes around them, it gets old and dries out...and can cause a leak. Also, perhaps the gasket of the intake pipe? I know on vr4s, the y-pipe gasket can leak.

3 things that will eliminate the boost leak there

#1 - vacuum reduction mod
#2 - replace the idle screw o-ring
#3 - replace the throttle body/intake manifold gasket

i had the same thing.. just hold ur finger where the screw is.. if the sound goes away, then get u the rubber cap thats supposed to be there.

and if that all fails, try the emissions plugs... i took the emissions off my car so i have 3 empty plugs that i had to cover, and the plugs keep coming off so i put black silicon on them and plugs it... and try the little one way filter on the back of the throttle body.
