Default Throttle blade set screw

what size is the little throttle blade set screw on the outside of the TB that adjusts how far open it is at idle??

i need to open it just a tad im not getting enough air at idle and i cant get an allen to fit in there for the life of me and am really not interested in pulling the TB off just for that

The easiest thing to do is thread the screw all the way out, and flip it "upside down". This will then put the head of the screw on the top, to make it easily accessible.

And yes, it's a T15. Make sure if you're turning the screw it's reset in the PCM for the TPS voltage. Otherwise you'll be showing inaccurate voltage even when the throttle isn't even open.

Once you get it set put a small drop of Loctite on it so it does not vibrate out of position

X2 on that one. I also did the same thing on mine and it really helps making it easier to adjust..
