P1518 - Intake Manifold Runner Control Malfunction (Stuck Open)

Guess is there are butterflies that change the airflow in the engine with RPM. There are some bushings that break or bind up occasionally and apparently that is what happend here.

Recommend replacing the upper intake gaskets and bolts at the same time (a couple of hour job I would recommend more for a pro technician or an advanced shade tree)
