Lamda or oxygen sensor is the one connected to your zorst. I don't know how many are aware, but supposedly these sensors last between 80k-160k km. There are things that might indicate a faulty one like bad fuel consumption, erratic idling, running too rich. The point is that you might have a faulty one and not know it. Using a GS-911 tool, hooking up to a laptop, you can see whether it works or not..and other stuff. So, who's got one?
