Trouble Code: po505.... need info!!!

Just recently i replaced my stock intake with a new AEM one, and the "check engine" light has come on, and also there is a "idle control system malfunction". Im pretty sure its due to something not being conected right but im not sure what. If anyone has any info on this problem or any advice, please share!!:)

i think you need to plug the nipple that comes out of your intake manifold on the back. check with the aftermarket intakes manifold - there is a nipple that needs to be plugged or you will throw codes.
