Code p2004 & p2005

[alexisrocha.s]

2016 Mustang GT
I just got a ported intake manifold (kept IMRC) fuel injectors and a new TB, before that my car was running perfect but now this code keeps appearing and every time I press on the gas I hear a leak like air is leaking.
Anyone know what could be?

P2004-2006 is related to the intake IMRC control... seems yours may be faulty, which is common on the Coyote 5.0.

Check the IMRC articulation shaft. In this thread, another M6G member repaired the broken IMRC shaft using JB Weld and it was fully functional again after the repair.

99% of the time, the IMRC failures are due to the broken shaft. Looking at images of the shaft, the break is occurring because the diameter of the shaft is too small for the torque being applied by constant activation.

Great points from Cobra Jet.
Also, you mention you just got a ported intake manifold, so whoever was in there doing the work (i.e., you or someone else) and nature of the fact that IMRCs are related to the intake manifold, the IMRCs themselves should be checked for possible issues post-install.
