If your AFR's are moving around after 10 min or so, you need to check the voltage to the WUR. It should be a solid 12v or a bit better, depending on your elect system. As you know, the bi-metallic strip reacts to temp - whether from the engine (heat soak) or the 12v source (for cold starts or cold days). The idle should not hunt (or system pressure) if the WUR gets 12v even at very low temps - the system was designed in Germany for all types of injected cars for all types of weather.
