Message sign of trouble if they say your car is running lean. You need to check the FI (not just for corrosion, but check the resistance as well - 10~14 Ohms). Are you using an aftermarket fuel filter? If so, get rid of it and replace it with a Nissan fuel filter.

Check for vacuum leaks and boost leaks as well. Look up (as in search) the 6 P's post for other things that you can inspect/repair.
