Im Anschluss habe ich die Drosselklappe ausgebaut und mithilfe des Stellgliedtests festgestellt, dass sie einwandfrei öffnet und schließt. Hier die Messwerte:

Die Klappe ist meines erachtens nur normal verkokt:

Das Fahrverhalten hat sich eigentlich nicht verändert. Ich merke lediglich beim Abstellen des Motors dass er sich mehr schüttelt als vorher, was wohl durch die offene Drosselklappe kommt.
Jetzt kann es eigentlich nur noch an dem P0123/P0121 Fehler liegen. Wo sitzt der G69 (Drosselklappenpotentiometer), bzw wie kann ich prüfen ob er korrekt funktioniert? Hatte schonmal jemand ein ähnliches Phänomen?
