The fuel pressure is too low and the CEL throws an adaption fault because it cannot supply enough fuel to satisfy the O2 sensor without excessive injector duty cycles?
Could be the fuel pump, fuel filter, fuel pressure regulator. Check for spit ends in the hose from the throttle body to the absolute pressure sensor. Check that the O2 sensors get a good ground. Check resistance from the sensor bodies to a good ground.
Check the condition of the connector surfaces for the front sensor.
miles?
age of filter?
Any sign of a low pressure in the fuel tank when you open up the fuel filler?
