I installed an air fuel gauge in my 97 ex. Don't really need it yet however i got a good deal on it and wanted to mount it in my radio block off plate.(looks pimp by the way:tpp So anyways it is hooked up and getting signal, i know this because the reader changes when it is at full throttle. However my friend told me that at idle it should bounce back and forth from lean to stoich.But it hangs right around lean and also has one bar lit up all the way at stoich. He says it may be my o2 sensor. Just wanted to see if anyone else had encountered this.
