What else should I look at or order? Can the AOS cause this but not everytime? Vacuum on the oil filler feels very normal.
To "feel" vacuum at the oil filer is not at all an accurate way to diagnose an AOS issue.
You need a proper gauge to test the vacuum. Do a search here on the forum you should be able to find some threads on the issue. They should show a picture of a gauge and the testing spec.
