csa Posted July 6, 2009 Share Posted July 6, 2009 I’m having a bit of a problem with my afr numbers on my AEM UEGO. When starting the car they sit almost steady on 14.7 and not really moving about even when giving a bit of throttle. When driving the start to vary a bit, but not much, and sometimes they even sits steady at 14.7 when moving slowly up through the revs. at WOT it shows around 14.3 but not any more rich than that (normally it's around 11.3 at WOT). Coming off the throttle it shows no higher than 15, and it normally goes off the chart in high revs. I had a brief talk with Ryan (who mapped the car) and he suggested to look at my pump installation, as we had some issues with that during mapping. The hoses down there had some slights bends allright, so I changed them, but it’s still the same. Should be said, that the car drives and feels exactly the same, which suggests to me that it’s the wideband playing tricks on me. Could the sensor be in need of a cleaning and if so, how to do it? What to do next? thanks Quote Link to comment Share on other sites More sharing options...
