I've been dealing with the same issues. Thanks to the OP I have saved thousands of dollars as I was about to go down the same route replacing the injectors / coils and so forth.
My rough idle seems to have gotten better in the cold weather for whatever reason.
What I'm dealing with now is after a couple of minutes at idle the car forgets what rpm to idle at and creeps up to 800 or so without being prompted by a stumble.
Part of the crew.... never had a misfire or code but rough idle.
