    Default code help...

    hey guys I wasn't sure where to post this so I just posted it in the noobie section.
    i got a P0401 code today which says
    "Exhaust Gas Recirculation Flow Insufficient Detected"
    umm...I have a turbo back exhaust with a test pipe. i also got 750cc injectors. as far as fuel goes thats all i have done that I can think of. the map im running it is only pushing 13psi so its barely pushing the engine. Any ideas will help thanks guys.

    Check the vaccum line going to the EGR valve to see if it popped off or if it has leaks. It could be either the EGR valve gone bad, or the EGR solenoid.

    It may have a cut in it. They are black to so it is hard to see unless you take it off.

    Ok well I checked it out and it seems fine. I cleared the code and if it comes up again then I'll take it to like fftec or someone to check it out in more detail.
