i did some more research and found it was fuel system lean, bank 1. how do you fix this?

Wrong section as you are in the Q45 Forum.

In any case, you need to start with downloading the FSm for the vehicle.

See if it is here:

If not, you can get the FSM and TSB at:

http://www.nissan-techinfo.com/infiniti/

foo a one day subscription fee of $20. Therein you will find diagnostic procedures. Might try the pathfinder and infiniti or nissan online mechanic forums also.
