Had a similar issue, changed plugs, and went with aftermarket coil packs, fixed it for a little bit, then the coil packs started acting a fool, had to pony up some cash to buy OEM coil packs, never had a issue after that.

Hi Wilsosk and welcome aboard,
On your battery check the wires(2) that go to the negative post. Make sure there's no corrosion between the wires and when you add the battery connector to the wires make sure its good and tight. We have had 3 vehicles not running right. Slow to accelerate sometimes or not at all. After doing this to 1 auto and that fixed it I checked the other 2 vehicle and that fixed them as well, Even though the connection to the wires was tight the corrosion was the problem on one of them.

Start by replacing the spark plugs and see what happens, if you are still getting misfire codes after new spark plugs, then the coils are the next suspect. Try this trick, if you are getting a misfire code in say cylinder #1, the swap the #1 coil with #2 coil, and then test drive it again. If the code then goes to #2, then you've found the faulty coil.

You could use a mustache, nice smile though.
