Good idea. sounds like 'spark" related. I dont like "testing" parts to diagnoise problems LOL! Also when you pull out the coil pack; see the tube that connect to the spark plugs have any "carbon" tracking and the spark acutally ground to the wall instead of to the plugs. Usually they they greyish color.
Try a bottle of 'Fuel Injection" cleaner from Techron.
