BUCKETHEAD

i have a 88integra witha d16a1 block bored .30 over. second gen zc head p&p by port flow with claysmith cams, jg p&p tb and inatake mani. i ported a apexi 4-2-1 header and have been using it for a while. the pnly problem is i throw an o2 code with it. the o2 was at the collector but since im obd0 i got a new bung welded to the primary runner right before it meets the secondary. i plugged the one at the collector and replaced the o2 at the primary. anyone know any reason its throwing the code? and also do you all ahve your map vacume line going to the intake mani or the tb?
thanks for the help. i would ask people on g1teg.org but there all tools and odnt know ----. guess thats why there drivng g1 tegs.

proably a bad o2 and a poorly running car obdo o2 codes are very common and a result of a poor tuned vehicle
