I check them and i change them with new br9ecm and i went for a ride again it is black brown it seems ok from jetting Dave and i change coils too! maybe is something electrical because in 1st/2nd/3rd gear it is ok and goes 12k rpm! I check the tps too! It is ok I am getting crazy with my nsr

I am thinking about wire splice in gps i read that wire splices cancel each other and It have neutral ignition anyone know something about this?
