Hi Malcolm,

That fault code tells us that the air-fuel ratio in the car is too 'lean' - meaning too much air for given amount of fuel. This could be caused by a number of things, including an air leak in the system or an error with the airflow meter. You'll have to get a good mechanic to trace the source of the fault, which is likely to be time consuming. I would advise you get the work done, however, as an incorrect air-fuel mixture could lead to engine damage.
