i got 6 o2 codes. which doesnt make sense to me because i just installed 2 new o2s for the front after i got in my cattman headers.

so lets just pretend i bought a nitrous kit do i really need to fix the codes before installing it? will it mess with my a/f etc?

 

you should be fine get a wb to confirm your a/r and tune the jetting according but there is nothing wrong with routine maintence

 

maintenance before mods lol. try and reset your ecu and wait and see what pops up .

 

What kind of kit did you buy and how much are you planning to spray?
