Now to answer your question. Anything from an Oxygen Sensor to a simple adjustment to trying to find a leak in a vaccuum line and probably a certified mechanic.

From the FSM:
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual
mixture ratio can be brought closely to the theoretical mixture ratio
based on the mixture ratio feedback signal from the heated oxygen
sensor 1 (front). The ECM calculates the necessary compensation
to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large
(The actual mixture ratio is too lean.), the ECM judges the condition
as the fuel injection system malfunction and light up the MI (2
trip detection logic).
Malfunction is detected when fuel injection system does not operate
properly, the amount of mixture ratio compensation is too large.
(The mixture ratio is too lean.)
Possible Cause
+ Intake air leaks
+ Heated oxygen sensor 1 (front)
+ Injectors
+ Exhaust gas leaks
+ Incorrect fuel pressure
+ Lack of fuel
+ Mass air flow sensor
Oh yeah, btw did ya go here first?
