Just wondering, Have you checked the EGR valve? From the pictures it looks fairly new. They have a tendancy to carbon up and hang open. It creates a slight vaccum leak in the intake which can cause a unstable idle, hesitation and chugging on acceleration. It won't set a code either. Also check to make sure it doesn't have vacuum at idle, the solenoids do fail occaisionally.
