2002 Nissan Xterra Q&A
2002 Nissan Xterra Question: cant get rid of codes and skip at idle 0304 0505 do i need to change injector?
With what you have done already, you might as well change that injector......you can swap injectors and see if code goes away. If injector is faulty, the code will move to the new position and you will know it is faulty. Clean it up best you can while it is out. The p0505 is for the IAC valve (idle air control) may need removed and cleaned or replaced. - csubak30
