Look around your purge valve and see if there are any cracked vacuum hoses. Happened to me a while back.

I think you guys helped me here. Had an intermittent bog on acceleration and I found one of the clamps on the hose that comes from the vacuum valve to another fitting was moved down from the end. I had taken the hose off when working on my intake manifold and had not moved it back up. May have had a vacuum leak.

At least for today, do not have the bog.
