Honda Fit 2007 feels like it's going to stall

Hi,

I recently noticed my honda fit 2007 feeling like it is going to stall in a few cases:
when I turn on the Air Conditioning and drive
when I drive in reverse
When I am idle

It is not as bad as it could be - car actually stalling - but I would like to know what it is so I can fix it now and avoid the headache.
Just had a combined 60.000 and 100.000 mile service done and that did not fix the problem as I was hoping it would.
Thank you for your ideas.

Clean the Air Flow Sensor with sensor safe cleaner. Put some Techron in it it too. This has an electronic throttle body. The ECM controls the throttle plate to control idle. I would clean the throttle plate. You need to put the key on, but not start and press the gas pedal down to open the throttle plate. Don’t force open the throttle plate manually. You can damage it. Then clean it with throttle plate front and back and the seat where the plate seals to the throttle body with throttle body cleaner.
