so I just got my 98 kouki about last week. when I bought it, the guy said that the only problem was that my front o2 sensor burned out (which I changed 2 days ago). but then the CEL was still on, which I found odd since that was the only flaw with the car. I went to a friend, who's a mechanic, told me that the tranny has been switched from automatic to manual. He said that the CKP sensor has been modified, it had a washer and tape for some reason so it could fit in the tranny which, he installed a new one for me. And, the downstream o2 sensor has been converted to an upstream and also burned out (idk why lol.) I also replaced the o2 sensor near the catalytic which was the converted one. Still, the CEL is on. My car also doesn't have a neutral safety switch. Any reason why my CEL is still on and how can I take it off? Thank you!
