Causes and Fixes P2004 Code: Intake Manifold Runner Control Solenoid Stuck Open Bank 1

How to fox a P2004 Code: Intake Manifold Runner Control Solenoid Stuck Open Bank 1
An intake manifold runner control (IMRC) opens and closes flaps inside variable intake manifolds, which optimizes airflow into the engine.
Depending on the vehicle, the solenoid can be electric or a combination of electric and vacuum controlled. It receives its signal from the computer (ECM/PCM).
Each manufacturer has a unique IMRC system design.
Possible Causes of a P2004 Code

Possibly worth noting is that 4cyl boxer motors have a 2 bank design as well.

I'm getting a p2008 code on my 69 Dodge Coronet 392 hemi swap. I thought it was the actuator so I replaced it..didn't help. I've checked the connector it seems fine. Ideas?

The tube that connects to intake manifold runner solenoid is broken. Could that cause p0106 that i'm seeing?

On my fusion I replaced the whole intake with hoses and both solenoids and I erased the code and it immediately comes back.

My Imrc keeps working open and closing constantly even at idle and low speeds and I have multiple codes
