Order of inspection
P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1) Medium
The P0130 code means the signal from the upstream oxygen sensor is not behaving the way it should: it does not oscillate, it sits stuck, or it responds too slowly. Before you replace it, check whether the sensor is correctly reporting a mixture that really is wrong, because in that case the sensor is not the problem.
