There are three plastic tri-colored tubes that are extremely brittle in and out of the EGR and one to the upper intake manifold. Check for cracks, broken lines.-Get two cans of Seafoam from auto parts store. Put one full can in gas tank, use second can to clean upper intake with engine running. You can put a drinking straw in the can of Seafoam and hold the end sticking out up to the PCV valve. Best option is to use any vacuum line to draw it out without stalling it. I treat mine every 5K miles. This is not a fix to your high idle issue but helps ALOT to eliminate any second guessing.Post when you have it fixed! I want to know. Thanks. Good luck.</blockquote>
