what should i do i recently ported and polished the head on my 95 si h23a1 and installed gude cams new valves, springs and retainers. now the car runs good but when it sits at a light or stop sign idle bogs down and throws a code 43 for the fuel systme i was thinking it is too lean but i hear no pinging under full throtle so any help is appreciated.

 

I had it too. It appeared the white wire near O2 sensor got short.

 

i was thinking it might have something to do with the o2 sensor but that definatly points me in the right direction thanks man
