my b16 is throwing a 1, 17, and like 43 or some **** on a PR4. now I proabably need a new o2. and my idle is kinda jumpn around not just on the cold idle any more. further more at high rpms the fuel is cutting out now i don't know if i need a fuel pump, main relay, or what anybody want to shed a little light on the situation.

 

Also once and a while my fuel pump won't prime my injectors and it won't start
