Hey guys, just installed a plate kit on my 2000 ls1 trans am.. Now I'm having an issue with my idle due to the plate kit. I've adjusted all I can on the cable to allow the throttle body to shut somewhat. It still idles around 1900 rpm. Any ideas or tips would be greatly appreciated!

 

Did you use the throttle cable relocation bracket? If you did and everything is adjusted correctly, you may have a vac leak. Check all the gaskets and make sure everything is sealed tight. Another thing that can cause that would be the IAC malfunctioning. Make sure it doesn't have any damage and is hooked up correctly.

 

that ended up being the issue. Had to fab up my own bracket. Thanks for the help!

 

In case anyone else has this same issue here are some pics with measurements if you need to make one in a pinch.

 

Thank you for sharing those dimensions.

 

If anybody needs one of these brackets we have them for 78MM, 90MM, and 102MM. They are only $14.99+shipping-

 

You're very welcome!
