Need throttle posistion screw size!!

Anyone know what size it is? It looks like it's a star tip but I'm note sure. Thanks for any help!

It is a Torx Bit and the size for the TPS screw head is #T-25. Hope you have an assortment of Torx Bits, if not, a set of Torx Bits would be a good investment to maintain your F-Body.

Obsolutley...invested in a bunch (of tools in general) before pulling the motor out. I should have checked the size out before everything went back together but I was too anxious to have it running again. lol!

I had the 'proper' tool but in my car I couldn't get it to fit in there to adjust the IAC and ended up using an allen wrench fit in and adjusted the IAC.

I am talking about the screw that you can use to actually raise the idle. I guess it would be a throttle stop.

I know, that can be adjusted using an allen like I said. My TB had clearance issues.

Good luck
