190e high HC/CO
Hey everyone, I have a question that I hope I can receive help on. On emission my 89 190e 6cyl blew high on HC/CO = Hydrocarbon & Carbon Monoxide. I had the valve seals replaced, and my O2 sensor light is working but not on to indicate a replacement is needed. I have given it a tune up also my HC = 3.0535 & CO =48.6325. Any ideas?
