IACV (Idle Air Control valve Location) Car idles when driven
 

Hi everyone I am new to the Acura Form and I had a question, I just replaced my intake manifold on my 2005 Acura RL a couple of months ago and everything has been working fine. But when I drive the car the engine seems like it is going to cut off and then it idles back up. Now I put it on the computer and the code it gave me is PO2279 air intake leak. Now when I looked online it said it might be IACV ( Idle Air Control Valve) may need to be clean. My neighbor said this is usually attached to the throttle body because he has a TL. But for some odd reason I do not have it on my RL throttle body. Now I look into replacing the purge valve but just not sure where to find this leak. I replace my spark plugs and coils and it is still idling when I come to a stop. Can someone please help find where the IACV ( Idle Air Intake Valve) is located on this car? It would be greatly appreciated!

Thanks
