So i'm reading up on adjusting the throttle screw for idle compensation on cars with larger cams, but for the life of me I don't see the throttle screw anywhere on the throttlebody itself, am I missing something??

 

Look at the closed position throttle body stop, where the rotating piece rests when it's closed. This piece lands on the screw, you can adjust it from the bottom, but might have to take the TB off.

 

You almost HAVE to take it off to adjust it...a big pain. That's why some of the throttle body porters turn the screw upside down so it can be adjusted from the top.

 

Ahhh.. and here I am scratching my head lol! Thanks!

 

If you screw with the screw you may have to do a
TPS relearn to get idle TPS% right (back to 0%).

Wonder why people don't drill a pair of holes and
put an idle air bleed screw like carbs. Looked at
that way back, seemed doable, but with tuning tools
there's no need to make shavings.
