    Sounds like youve got the standard codes for headers (need to get a tune!)... and check that vapor solenoid, you may have to move/unhook it when installing headers and the tubes aren't seated correctly.

    Yes the GM tech info says both banks oxygen sensor 1 & EVAP are on the same EMISSIONS1 circuit.
    There's nothing else on that circuit.
    Fuse for Emissions1 is F33 rated at 15A.



    It probably wouldn't hurt to check F32 as well , as although this is listed as EMISSIONS2 and supposedly for both banks oxygen sensor 2's, GM have been known to confuddle the naming conventions on oxygen sensors.
