i think i might have found a problem with my setup that i would not have seen without the wideband i installed this weekend. im going lean after 4k rpm. i think its shoddy vacuum lines. not that my lines are bad - theyre all brand new braided, copper and rubber lines. just too many on my fpr line. changing that right now.
