ok i went out and let it warm up unpluged the iacv and it went to 5-6rpm. The orginal one i had on my motor when i took it off didnt have a screen so i replaced it with another one from my other a6 motor with a screen. I cleaned it and checked the bottom for debre. When I reinstalled it and checked it today i noticed theres a dampness around the bolt area from coolent. I didnt replace the gasket on the bottom could this be the cause? Also this manifold does not have a FICV on it.And heres some shots of my vac lines






middle goes to BOV right to fpr and left feeds boost gauge and WG and that thing on the firewall anyone know what that is
