air fuel ratio going to the rich side

I own a b13 1994 nissan sentra with a SR20 Jim Wolf computer and when I took the car to the dyno the fuel map always showed that the A/F mixture never passed 11.50 over 3800rpm and from there on to 7200 rpm it went south to a 10.00 I called Ben at jim wolf and I m suspecting flow meter problems and I will like to know if an intermittent flow meter will trigger codes on the ECU or it has to be tested in other way than diagnostic test to really know what going on?
