OBD code P1131 in a 1995 Ford Mustang indicates a problem with the bank 1 oxygen sensor, specifically that it's reading a lean condition. This typically means that the engine is receiving too much air or not enough fuel, which can be caused by issues like vacuum leaks, fuel delivery problems, or a faulty sensor. Addressing this code usually involves inspecting the air intake system, fuel injectors, and the oxygen sensor itself for proper operation.
