Engine hesitation

I have been experiencing this intermittent problem for some time.The engine will begin to run rough at partial throttle. When I stop the idle seems to be fine but it does hunt just a little. If I continue to drive the check engine light will come on. If I turn off the ignition and restart the engine often the problem does not come back for the remainder or the trip, and sometimes it does. (Sometimes I don't have the problem at all!) I have replaced the engine temperature sensor and the lambda sensor. I'm wondering if the problem could be related to the idle control valve? I have the Durametric analyzer and it doesn't show any stored dme codes. Any ideas?
