When you replaced the ignition components, did you also replace the coils? And did you have a check engine light on? If so, did you have the computer scanned?
If you've eliminated the ignition system as a possible cause, then the fuel system is the next target for diagnosis. Begin with the fuel filter. A clogged filter will allow the engine to run at idle but when you accelerate it'll bog the engine down because it can't flow enough fuel to supply the load. But if you're sure that only the right bank is misfiring, then it'll have to be something on that bank causing the problems. I'd believe it would be the injectors are clogged or the wiring for that side is faulty.
