Adding that you should carefully inspect the coil boots- the rubber part that connects to the spark plug. Mine were bad around that time. The boot simply pulls off the coil- although it's easier if fold the plug end back past the coil first to break it loose. Look for cracks or other signs of obvious rubber failure. Boots cost about $5-8 each, and come with the spring and magnet inside. If you see any oil on the boots, then you need a valve cover gasket. Always install spark plugs with a dab of silver anti-seize on the threads.
Good call on the boots. I forgot I did that when I did the plugs. Really easy and fairly cheap for a little extra protection.
