Vacuum line leaks all around you EGR, pcv, and any other vacuum lines. The vacuum lines originate along the firewall and branch out. You should be able to find a vacuum line broken or disconnected somewhere in the engine, starting with the EGR valve and any line running towards the upper intake manifold or throttle body.What codes I did not list were not in the manual.</blockquote>
