ah the infamous P0171 and P0174. You have a vacuum leak. Common area on the taurus is the hoses from the upper intake to the vacuum tree. Start the car, open the hood, and start moving the hoses around near the brake booster and any hose that connects to the upper intake, also the PCV hose. When you hear a hiss, this is the hose that is cracked. Sometime a small plastic elbow will rot and crack as well. Ask me how I know.
