DTC PO171 indicates a lean condition, this is caused by the air flow meter located just behind the air filter on the intake tube, here is how to fix this trouble code: Remove the air flow meter and clean the very small platinum wires inside the housing of the af meter with an electronic circuit cleaner, it is important not to use anything else, you can get it any radio shack or electronics store, just spray it into the opening to clean the accumulated gunk off the wires, clear the DTC and you will be good to go, install a new air filter.
