It dose not sound like a failing coil and or even an injector. Have you checked to make sure there are no vacuum leaks in and around the intake area?
I would also run a regular compression test and then do a running compression test on each cylinder to see if perhaps you could have a valve sealing concern.
I would still run the compression test to at least rule it out. Injector are usually either good or bad. One other thing you may want to do is to have the injectors professionally cleaned in case you dealing with sludge build up on the tips of them which could affect engine performance.
