I had 2 idle circuits completely clogged, it wasn't firing on those 2 but i still had vacuum activity on them.

I was figuring that if the valves are adjusted and opening when they should, the piston activity even with no firing should be pumping air.

Could it be sucking air from somewhere else like under the throttle plates? but you check it.

Does the throttle plate open when you play with the linkage on #6.

Could be that for some reason the intake valve is not opening or that the exhaust valve doesn't close all the way???

Just thinking out loud.
