The drawing you provided on another post shows one of the two connections. It is the hose that goes to the canister in the lower right corner of the drawing. Most likely the other hose goes to the Power Brake Booster. It gets a direct vacuum source from the engine as well, and it is usually directly from the intake manifold. That is not depicted on this diagram.
code p 2004 has two references
intake manifold air control actuator , bank 1 --actuator stuck open====causes ---wiring---intake manifold air control actuator ---mechanical fault
second reference is
intake manifold air control solenoid , bank 1 --solenoid stuck open===causes ---wiring--intake manifold air control solenoid ---mechanical fault
probably means the same as what you have but in a more easy to understand method

when cold idle is going, listen to intake manifold with hood open. This will involve getting real close to the intake side of the engine. If you hear a whistle or air draw from anywhere around the intake, there is an air leak to the engine. The intake manifold gasket maybe cracked allowing air to bypass the intake sensors at cold when the gasket is closed. But when it warms up, the gasket allows air to bypass the intake and causes a stumble, pause at partial throttle or a wondering idle. If you increase the idle speed, it confuses the cpu and causes the engine to run eratic.
The intake manifold draws air into the engine where it meets the fuel injectors. It must have an air tight seal (meaning all attaching components be firmly in place) in order for the engine to function properly.
your controls for floor,vent.defrost ect. is in default mode due to a loss of vacuum. you need to inspect vacuum lines for being lose cracked,or disconnected.hose will run from engine intake manifold through firewall into the dash.i'd start at intake manifold looking for bad hose
"Canister" usually refers to the charcoal canister. It's part of an emissions system called the evap system. It's a canister that contains a refined form of charcoal that absorbs evaporated gasoline from the fuel tank, and stores it until the computer opens a valve and it is burned by the engine.
if it's 5.2 or 5.9 engine,the intake manifold plenum pan gasket may be drawing oil from lifter valley of engine..remove air cleaner and check down inside manifold with throttle plates wide open and look for oil pooling inside intake..if there is oil in there,you to remove intake manifold and replace gasket and bolts holding rectangular pan to bottom of intake..you will need intake gaskets as well..suggest going to dealer for parts..fairly inexpensive as well..i hope this helps
The vent is controlled by vacuum. Check the condition of the vacuum hose associated with the vent control. What is happening is when you decelerate, the intake manifold vacuum increases, and a diaphram is slightly pulled giving you air in the vent but very little. In normal condition the diaphram wont even pull. Solution is check for a vacuum leak in the vent control trace it coming from the intake manifold.
The exhaust leak is almost always broken studs on the exhaust manifolds. It makes a tick noise when cold and usually goes away when the engine warms up. After a year or so, the noise doesn't go away.
Your heater-a/c air intake is at the base of the windshield through the screen on the passenger side. WHen the exhaust leaks from the manifold, the exhaust gas gets sucked into the air intake.
You can put the heater in recirc mode and it will draw air in from inside the car instead of though the outside air intake. You can't leave it in recirc for long in winter or your car will get ice or fogging on the windows from too much humidity. Take it off recirc after 10 minutes.
