I had a roaming misfire which would come and go randomly. Ended up 99% sure being an idle air actuator slipping to much O2 in at idle. Ended up replacing the throttle actuators too while I was in there since my mileage was over 100K and I didn't want to mess with the getting the plenum off and on again. Those throttle bodies closest to the fire wall can suck a fat one.
