I recently got SES light on and I purchased a OBD II reader and found out the DTC P1518 (IMRC Stuck Open).
But, after opened up upper intake manifold I found out that no runners appear to stuck in opened. Each pair of runners have one open and one close. The following photos for two pairs of runners on firewall side, one left side and one right side from driver's point of view.

Looks like the runners are fine unless I am mistaking what the runners are. Although the carbon buildup is pretty bad.
So, what is next? the controller and related cable? Blind Seafoaming?
