    Go for hose first check them out one by one . With replacement hose . I had a crack in mine. Start with the cheaper fix before you put more money into it .

    Most common problem is a clogged EGR port in the intake manifold. Try removing the throttle body and check to see if there is any carbon build up. I cleaned mine awhile back and and erased the code with my scan tool, haven't had any problems since.P1010714.jpg
