Kia - Sorento :: 2006 - Idle Is 2000 To 2200 RPMs On Cold Start

I have a 2006 Sorento, Idle at start, when cold is 2000 to 2200 rpms. When engine warms idle comes down to normal, 1000.

Replaced several vacuum lines, none showed any leaking but replaced to be sure.
Replaced the PCV valve, the old valve was not closing as it should and the replacement seemed to work some.
Replaced the Idle Air Control Valve and checked the old one for movement, moved an 1/8 of and inch from when cold to when hot. The new IAC did improve the problem some.
Tested throttle position sensor voltage, was good through range of motion (including being tapped on to simulate the running of the engine).
Sprayed carburetor cleaner around the engine when cold to look for a possible manifold leak, nothing noted.

Noticed one area that brings down the high idle when sprayed with carburetor cleaner is in the front top center, around a small plastic cylinder which is part of the intake system and has a vacuum manifold which changes the position of the cylinder with engine operation. I have two pictures of the area attached, the white cylinder is at end of paint stick, the vacuum manifold is to the right of the paint stick and yes there are vacuum lines not hooked up in the pictures. Hoping this is not a manifold leak.
