i have the same problem with my 95 accord v6. I have read somewhere on a forum of someone else that had this problem and they had found out that it was the ignition wire that needs to be replaced. I hope i am remembering this correctly cuz this is a $25 part from honda. I have been searching to find that post in who knows what forum to verify it. My car usually doesn't do it, but it does occasionally. yesterday it did a lot, and also i felt it affecting the engine like how you described. but i filled up my gas tank and it didn't do it today. If you find out about this, post it cuz i need to know for sure too.
