niedrige Drehzahl bei warmem Motor ?!?

[Eike]

Je leerer der Tank ist, desdo eher läuft der Motor unruhig! Werde ich die Tage machen.

Hier noch ein paar Diacom-Daten (Leerlauf im Stand):

Ist das normal das die Oxygen Sensor Voltage so schwankt?

Vielleicht kann ja Jemand was mit den Daten anfangen.
Wenn es hilfreich ist werde ich noch eine Testfahrt aufnehmen und grafisch darstellen.
