My check engine light seems to come on when I drive the car cold. After the car has warmed up, if I reset the light it stays off. I've gotten the code read, and they tell me it's Oxygen Sensor 1 Bank 1. I changed what I thought was that O2 sensor (front driver side), but I still have the problem.
Does anyone know which sensor is "Sensor 1 Bank 1"? Does anyone have any other suggestions?
Thanks a lot.
