The Oxygen Sensor of my 230E 1992 has 90 kmiles, and the HC emission reading is 74 ppm while idlling. I consider it a bit high because where I live the standard is 100 ppm, max value, and I also have a 1998 E240 with 28 kmiles, which is reading only 4 ppm on HCs. Both cars have very low CO readings though. The 230E has a slight unstable idle too, warm or hot. Besides, we here in my city have a very severe pollution condition right now, and the litte voice in my mind is telling me to do anything to help. Under this circumstances, is it worth to change the sensor? Do I need more information to know wether it is working properly or not? Thanks MMansilla
