Question TB Idle screw air leak

Hey guys, I noticed my car behaving funny suddenly when the a/c is on, she would drop real low below 1000 rpm momentarily like as if i had a vacuum leak and sometimes stall.

I did a boost leak test and ive got bubbles coming from the idle adjust screw and what seems to be the bolts that hold the TB to the intake... this is minor leakage nothing crazy but a leak is a leak...

Anywyas, I pm aby@mil.spec as i would like to get a new tb gasket and shaft seals...

air comming out from the bolts-related to the gasket right?
air comming from the idle adjust screw- is that reated to the shaft seal somehow?

anyone seen this before...?

Air coming from the bolt would be due to the gasket. Air leaking from the BISS screw would mean a leaky BISS o-ring (assuming they're designed the same as a DSM TB). Talk to Aby and see what he says, I'm sure he can set you up with all the new seals you need.
