Maybe it is just too cold here:

♦Engine temperature between 5 °C and 100 °C
♦Intake air temperature between 10 °C and 100 °

Engine was cold, temps were about 37 degrees F / 3 degrees C.

Next move (tomorrow): Let the engine idle in the garage for a few minutes or so, in order to raise the temp of the air within the engine compartment. Then do the above procedure for a third time.

.... Seems like it certainly should not be this hard ...
