Looking at the data at idle warm car I am at 7.5% rich on the short fuel trim. The narrow band o2 is at .015 will go to .5 volt when gas pedal is pressed briefly.
.015 seems low and indicates lean fuel, but the trims are rich. Not sure where the base line for either should be. when I add propane trim goes lean as expected. o2 stays the same. I do not have access to wide band o2.
No vacume leaks. Any advice?
