SOURCE: P0101 p0171 p0174 engine codes
Those are lean codes and a MAF (P0101) code. Make sure the MAF sensor is plugged in, and there are no leaks/ loose hoses between the air filter and the engine. You may have a vac leak at the intake also, but check these first, If all appears OK a repair shop will need to check it out for you.

well go back and ask for proper print out of what the emmisions readings are ,i cannot beleave that a vehicle test station can fail a vehicle and not tell you what the emmisions readings are but give you a lot of useless p numbers ,dont they put a probe up the exhaust and test it properly ,They would have field day trying to test europeon cars here in europe with all the encrypted software used on vehicles here and the vehicle shutting its self down with the immobilisor and throwing out code p whatever for illegal access to the ECU.any way try changing the lambada sensors as i think that this is what code P171 and 174 refer too

check for vacuum leaks or a faulty mass air flow sensor. all the codes have to do with engine too lean(too much air).

seems that your mass airflow sensor has failed. it's located between your air filter and your throttle body, and looks like a short plastic tube with a small module and a three or four wire connector on it. start with the classic "screwdriver test". start the engine and lightly tap the plastic tube with the plastic handle of a screwdriver. not too hard, but hard enough to let it know that its being tapped. if the motor reacts to the tap, the sensor is bad and needs to be replaced. the p0101 code is enough reason to replace it, but we mechanics like to whack them every now and then. :)
