Every time it has came on is when I was sitting in traffic. Sometimes it goes out by itself, sometimes I unhook the battery. Not sure whats going on? I can drive it for a few days before the check engine light turns on. I change my plugs every 50k miles and they always look real clean, so I just changed them thinking it might help and they was black and wet like the car is running rich. So I just changed the o2 sensor, which that code hasn't came back since. Unplugged the battery for a hour, code goes away, wouldn't get the light for a few days minimum. Ran the codes, 1 was the oxygen sensor and 1 for mass air flow sensor. Recently my check engine light started coming on occasionally but the car still ran excellent. It currently has 238k miles and has been extremely reliable. I have a 2015 chevy cruze that I bought new.
