Go get the codes ran at auto zone or advance auto parts they will do it for free. If the codes come up as a cylinder miss-fire then it is most likely a coil (being a ford). Write down which cylinder it is. I wouldn't replace any of the spark plugs , useless you have more than 100,000 miles. If you have to replace the spark plugs use BOSH double plautim or better. The cylinder placing is ( as your are looking at the front of the truck) passenger side front to back 1-2-3-4 driving side front to back 5-6-7-8. If you never seen a coil buy one so you know what you are looking for. The coil is held in by a 7mm bolt. Take the bolt out and replace the coil. Problem Solved. Estimated time 20 Mins with 60 dollars per coil.
