Coyote Gen 3 Intake Manifold Bank 1 Stuck Open, Code P204/205
Sorry it's stuck closed not open!!!
Can anyone help me with this issue? I had a similar problem around 1k miles but it seemed to correct itself. It now will turn over act like it will start and the just die. I thought it was bad gas from the winter so I replaced it but when I read the codes it was the Intake manifold. Thanks for any help I can get.

The engine should run OK with them stuck open. When the IMRC is deleted, they are locked open. If yours are stuck closed, you should be seeing different codes. Not P2004/P2005. In either case, do you have the vacuum lines for the IMRC installed properly? This is commonly missed because it's not in either the Ford Performance or Factory Five instructions. Discussed here for the Gen 3: https://thefactoryfiveforum.com/show...l=1#post351623.
