For P0132, check the little rubber elbow on the left end of the intake manifold, near the power steering pump. It splits and will set Oxygen Sensor and Fuel Lean codes. I had one once in the Volvo Dealership on an 850 Turbo, and it took me a long time to discover what the Air Leak was. It was hard to see. I had to 'feel' for it.
