I recently just bought a 98 civic LX and the engine light was on it when I bought it. I figured it was some of the aftermarket stuff under the hood but just to be safe I took it to autozone and got it checked. The guy said it was the front o2 censor and it would cost $86 just for the part. It was the only thing the analyzer caught so what should I do. I have been searching the web and found out that there is a lot of diffrent things that could be setting off the o2 censor alert. Thanks ahead of time
