This is the code I have stored in my continous memory. "Lack of heated oxygen sensor switches indicates lean (bank # 1)". What will happen is after a long time cruising on the highway in 5th gear ill get a check engine light that comes on but never stays on and goes off soon after. While the CEL is on the car will almost bog down completely, i'll press the gas and go nowhere. Is this a common problem ?would it be one of the oxygen sensors? Or is it more complicated than that?
