Ok I was doing some thinking today...and I read that the vacuum gauge on the instrument cluster attaches to the intake manifold to read the pressure inside.

With that in mind, if my vacuum gauge fluctuates slightly, doesn't that mean that there is not an even, constant amount of air entering the intake manifold at idle?

Does that mean a vacuum leak, or would the airflow plate be moving slightly based on electronic signals from elsewhere? What are your thoughts on this?
I have gone through every single hose on that engine...All the idle air hoses, all the ones that attach to the intake manifold and the one under the KE mixture unit.
