Neither symptom fits my situation. Butter smooth above 1200 rpm, idle is stable but shakey at 600-700 rpm with economy gauge reading half way in D with AC on.

The flapper thing inside the idle air valve moves freely and I don't think I can get it cleaner than it is.

Hoses look good. I've sprayed all around with carb cleaner and haven't found any leaks.
