In essence this is the same as the mechanic told me when we went for our smog tests (Fred's Garage in Redwood). The air mixture screw has little effect on leaness and hence pollution because the O2 sensor will always compensate. He demonstrated this by adjsuting the mixture and getting the same results. More surprising is that your idle is not easily adjusted. Does yours have an egr? If so, this could also be at fault since it could be easily pumping in more exhaust than necessary. The other item to check/replace is the O2 sensor - your idle will improve and outputs will be better. DC
