  • failing smog on hc's and co

    i have a bp swap thats failing hs and co. im not too good with emissions so im asking for a little help to see what tricks are out there

    at 15mph it passed:
    ---------measured-----max
    HC--------80------------92
    CO-------0.22----------0.55
    NOX-------374----------716
    at 25mph it failed HC and CO
    HC---------84-----------57
    CO--------1.55--------0.54
    NOX--------5-----------764
    I know its a piece of crap but im still faster...and its 100% legal!!!!!

    check your timing... i think high HC is timing related, my 323 gt failed big time cause my timing was way to retarded...
