why is my service light on
my car has the check engine light on i took it to autozone and the problem was p1137 which is the heated oxygen sensor 2 (h02s12) i have not got that changed yet also my low beams dont work i had to change the headlights out because the right driver side was dim and then would randomly turn bright again?? so i installed new ones but only the high beams come on and they dont even look like high beams just regular... now my service light comes on whenever i start the car......
