Yeah seems like 0.026" is the perfect application on your car. That's actually a really good thing because the gap isn't too much smaller than factory and since you're not running into issues you don't need upgraded coils either!
But yeah
shaneguags your gap is way too small and likely the cause of your misfires and rough idles. I had a hunch that could be the issue. I know alot of sources (including tuning companies) say to run a tight gap but that really should not be the case, they really should say to go as large as possible and gap down as your individual situation requires not gap to some specific number because it will work if you make so x amount of power. This simply is not the case and doesn't work. So IMO get new plugs gap at 0.026" or 0.025" (your pick) and move down as needed. Remember the bigger the gap the better.
