Just bought an integra was my aunts she was the first owner, she has a couple problems with it her check engine light is on which doesnt really bug me but also her maintance soon light is on do any of you know why it is on or why does it come on? Let me know please

 

Yeah your engine light is most likely on if your o2 sensor is bad(or you have an aftermarket exhaust that doesnt support the o2 ensor) your maintenance light is likely on due to the air induction sensor on your intake hose. If you have a cold air intake and didnt feed the sensor to it the light will come on.
