I have an 06 Dodge Charger 3.5L which had an engine light come on and was running rough...so i check the code P0406...EGR Valve. I replaced the EGR Valve and got these codes: P2008/P0660/P0113/P0108/P2172/P061a.
All of these codes refer to Manifold Tuning Valve/Short Runner Valve/Intake Air Temp Sensor/Manifold Adsoult Pressure/High Air Flow Vaccum Leak/ETC Level 2 Torque Performance. Does anybody know what this would be? ThanX

 

Sounds like a possible vacuum leak. It will cause all those codes, and its really easy to tear the little blue o-rings where the EGR tubes connect to the intake and not realize it.
