Answer
Hi Kevin;
Sounds like a misfire issue to me, but it could be the fuel delivery system just as much as the ignition system.  If you know how just switch the coils a round, and see if this changes anything.  They are a little fragile, so be careful when you pull them out.  Make sure you pull straight up, and not at an angle, or they can break internally, and you won't know until they start to misfire worse.  A fuel injection, and induction service should be performed so the system is clean, and replace the fuel filter as well.  That way you can limit your choice to just the ignition system.  Hope this helps, Kevin.  Good luck.
