I think my thermostat is stuck open because my car will not get above 153. but what do u guys make of the other codes? (p0128)

According to my wideband the car is running lean too. about 16-19 at crusing speeds. my interceptors show no misfire or anything out of the norm,tho im wondering if my wideband is toast.

P0133 Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 1)

P0137 Oxygen Sensor Circuit Low Voltage (Bank 1 Sensor 2)

DTC P1133
Circuit Description
Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. Heating elements inside the HO2S minimize the time required for the sensors to reach operating temperature. The powertrain control module (PCM) supplies the HO2S with a reference, or bias, voltage of about 450 mV. When the engine is first started the PCM operates in open loop, ignoring the HO2S voltage signal. Once the HO2S reaches operating temperatures and Closed Loop is achieved, the HO2S generates a voltage within a range of 0-1,000 mV that fluctuates above and below bias voltage. High HO2S voltage indicates a rich exhaust stream. Low HO2S voltage indicates a lean exhaust stream.
