Don't want to mislead you, the plug connectors/resistors Mr. Dalton referred to are what I referred to as the plug "boots". There are 3 in your car, 1 under each coil. I believe I used the incorrect terminology. As I mentioned before, I would replace these three connector/resistors and the plugs first because they are inexpensive. If that doesn't solve your problem, then consider changing the coils. Also, as mentioned above, make sure you have the right spark plugs.
