    95 Acccord EX Sedan (Auto)
    Running JDM H22A (Auto) w/ P0F ECU (SIR ECU)
    Injen Cold Air Intake
    DC Sports Header
    Magnaflow Catalytic Converter
    Custom 2.5 Exhaust w/ Vibrant Muffler
    VAFC-II (all settings at zero)

    (Note: This is my 2nd Engine. First one ran like shit and extremely lean then died)

    Emissions Problem:
    First Test:
    All numbers are good/Passed except for NOx which is almost double the limit.
    NOx 15mph @ 2137 (limit 1636)
    NOx 25mph @ 2289 (limit 1591)

    So went ahead and cleaned my EGR Ports and Valve which were clogged big time.

    NOx 15mph @ 3111 (limit 1636)
    NOx 25mph @ 3533 (limit 1591)

    WTF? The numbers got worse?

    Any ideas or suggestions? I purchased the Magnaflow Cat a few years ago but could it have gotten bad from the first bad H22? I have no CEL lights after the EGR cleaning. I NEED HELP PLEASE. Getting ready to sell my car if I can't figure this out.
