The P1130 is a very straight forward code and a very common problem on these vehicles. This code points to a problem with the A/F Sensor for Bank 1. This sensor is located on the side of the engine closest to the windshield, mounted to the exhaust manifold. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. If the visual inspection checks ok, replacing the sensor will solve the problem. Like I say, very common wear and tear fail item. Best access is from under the vehicle working upwards. Unplug the electrical connector and unscrew the sensor from the exhaust.
