Hesitation/Rough idle

I have a 91 Prelude 2.0Si...sometimes it hesitates under load and i get a rough idle intermittently...it almost feels like a miss, but everything checks out OK...fuel pressure is good, timing is good, I just cleaned out my distributor...not sure on the condition of the ignition module...any advice would be helpful...

anything? anyone? come on challanges are suppsoed to be fun, eh :D
