Diagnostic Trouble Code (DTC) p0133 refers to Bank1, Sensor1 being slow to respond. This may point to a failing sensor, or simply an intake or exhaust leak. Any gas leak can lead to unmeterd Oxygen in the system. This code may also be caused by fault wiring or connection on the sensor circuit.

Also did you forget to unhook the battery to reset to the other parts? Not saying your stupid but we are known to overlook the simple.
