When this happens, if you pull over, will it smooth out, or continue to idle rough.

Where do you set your GAV? I would suggest when this happens, open the GAV 1/4 open from where ever you have it. When you do, it will take 1-2 minutes, but see if that smooths things out.

Sounds like the engine starving. Many people will tell you that you set the GAV closed, 1/4, 1/2 3/4.... It depends on the car and the day. As a guy who worked on them 'in the day' said to me, "If Henry made it adjustable, he meant it to be adjusted".

check your fuel filter, and Let us know.
