1g dsm o2 readings off

Long story short Bought a from a friend that was working but he left the car in Georgia n flew back to the islands to live.  Car ran a rich idle. So i download the series1  program n pulled some fuel till it read 14.1-14.5 at idle.  Now the gauge said i was at 14-1 but the ecu was stuck at 19.5 n didn't move unless i turn the car off.  I've tried changing the source of the reading and the gains but once the car starts the gain is once at again stuck. Has anyone come across this type of problem before.
