    P0400 And P0421

    P0421 - Warm Up Catalyst Below Threshold Bank 1
    P0400 - Egr Malfunction

    A While Ago I Banged Off The Cat Cover Which Had A Braided Ground Wire Attached
    I Was In The Middle Of A Trip And That Was The Only Way So Does Anyone Know If That Will Trip A Code?

    Also I Am Changing The Downstream O2 Sensor For The 0421 Code

    What Should I Do For The 0400 Code?

    THANKS ALOT IN ADVANCE
