IAC block I have just installed my maggie 122 on my 04 GTO. While doing so I also upgraded my TB and now Im required to run a remote IAC. I was wondering if any one has done this before and if so, can you please give me or let me see the all the vacuum routings (PCV)in order for this to operate properly. The problem I am having is a cold start issue. Upon first start when cold the car takes a little longer to crank and when it does it will stummble at very low RPM (like it wants to die) If you feather the throttle for about 30 seconds everything clears up and idles fine and drives fine. Its just the cold start stummble that is a bit irritating. It has been dyno tuned by Texas Speed and they have made as many ajustments that they feel safe with but it still does this. Im thinking that I have either the vaccum routings wrong or the PCV routings wrong when I put the remote iac block in. Thanks.
