I have a 2001 Sentra GXE. The idling was uneven when start in cold in the morning. When shift to Rever or Drive, it goes down to around 500 and sometimes stall when start driving. The service engine light has not come on yet.

The mechanic diagnosis faulty bank 2 O2 Sensor. He clear the code but not change it. The service engine light came on later.

Thanks.
