PO133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
PO302 Cylinder 2 Misfire Detected
PO1131 Lack Of HO2S Switch - Sensor Indicates Lean
It sounds like you have a bad oxygen sensor. Also, has the misfire can be caused by the a lean mixture or a fouled plug. I would start with the bank 1 O2 sensor.
Let me know what you find.
