Nice green screen and diagrams. That must have been a lot of work.
Especially liked the effect for the magnetic field. Good content presented
in a professional manner.

From the bottom of my heart I hope I have helped your day go better even in
a little way.
This video has information in it for for all levels. We show you just what
an IAC stepper motor does and how it works. Then we show you how to test
the vehicle’s computer before you install one. I hope you enjoy it and
again thank you!

great video. i think you solved my problem. cheers
Good video. Gotta couple of things to add. One, may not be able to do this
on all engines, but a quick test to see if a vacuum leak is the cause of a
high idle is to remove the air intake tube from the throttle body, start
the engine, and while the engine is “idling” put a block of wood on the
throttle body opening. If the engine stalls, vacuum leak ain’t the cause.
If it still runs, then look for a vacuum leak somewhere. Also, another
possible cause of a high idle that wasn’t mentioned in the video is a
misadjusted TPS sensor.
Good Job
yes sir! thanks
