I'm trying to do the iac adjustment procedure and I'm having a hell of a time finding the right tool. What do you guys use?

I know its a t20 torx, but there's isn't much room there. The throttle bracket is right behind the screw so I can't get a screwdriver type t20 in there. To top it off, I have the Edelbrock strut tower brace and that happens to cross right in between the screw and the throttle bracket.

Wish I had a picture. What do you guys recommend?

Thanks.

 

I am not familiar with GTA's but on my Camaro there is no adjustment for the IAC. Its a sensor with a connector and it is screwed into the underside of the throttle body. You adjust it by jumping the ALDL etc. Do you mean the TPS?

 

I mean the idle speed adjustment.

Doh!

 

He means the minimum air adjustment screw.
Use a T20 bit with either a 1/4" wrench or dogbone, may have to remove the STB to do the adjustment.

 

Thats fine. Maybe I was confused. Do what Morley suggested.

 

i just pull the throttle bracket there on the plenum..makes life EZ. DONT allow those loose ends to touch the alternator "hot" source (i dont have the cover LOL)
