Idle air bypass screw starting point
 

I deep cleaned my throttle body and removed all the parts while doing so. I didnt note how many turns to seated the air screw was. Is there a default starting point>

IIRC, 3.5 turns out is a good starting guesstimate.

There are threads around this subject area, and the number I recall was between 2 and 3 full turns, mas o menos. I settled on 2.75 after cleaning the afm, resetting the afm sweep path, installing a new bypass screw, and a new O2 sensor. All vastly improved startup surging (original bypass was set at around 4.5 turns, so way lean), and off-idle bucking.

Are you asking a question about a hairdryer?
