Previously I used to remove the air filter and spray powerlube into the idle air port. Now I decided to try a new approach.
Step 1: Removing the Stator.
The connector I unclipped then the two screws holding the stator were removed. Once out you can see the bare rotor that turns the valve.
Step 2: Lubing!
A few squirts of powerlube onto the rotor and the stator cavity is all that is needed.
Step 3: Completion!
Once I mounted back the stator, I let it soak for half hour. When the car was started the idle was much smoother.
Not bad for a 5 minutes job.
