Cleaned throttle body again (DBW so very carefully with carb cleaner on cotton buds and rags).
Investigated a possible leak around the suction jet pump, nothing of note but will keep an eye on it.
Swapped DV for a fresher unit, nothing to report as my old one seemed to function OK afterwards with the "pop" test.
Gave it a good clean with my new wool mitt and waffle towel, then treated it to some Super Resin!
Noticed how tired the alloys are looking. Time for a refurb in the new year me thinks!
