I did my tune-up today and as I was changing the rotor and cap I noticed the CYP Sensor was dirty. So I unscrewed it and cleaned it off. Now I put everything back together and I have the CYP Sensor light coming on through my check engine light (code 9). The car runs a lot better since I changed everything but now I have that check engine light...any suggestions on what I could have done wrong?....do you think cleaning it made the ecu realize it's faulty?...is it something I have to fix before I can drive again?
