See this article on code P0171 that I wrote to help folks, because many shops aren't really clear on what this means and how to Diagnose this issue. http://repairpal.com/OBD-II-Code-P0171-and-P0174 The VIS codes will not set the Service Engine Soon Light, they have to do with little motors routing the air flow as it goes through the intake manifold. The most common cause for a P0171 is a defective Mass Air Flow Sensor, but be advised that these Freelander Intake Manifolds are known for getting little cracks and leaking, and in some cases have to be replaced ( a good used one will do ).
