Coil pack 2007 Ford fusion

Why are you replacing your coil packs? Usually they don't all fail at the same time. You should have six of them, one for each cylinder. I would advise you to replace the spark plugs too if you are going to all that trouble. The front three are easy to get to after you remove the engine cover. The rear ones , you have to remove the upper intake and all the hoses. Go to youtube to search for a video and only replace one coil and plug at a time so you don't swap the electrical connectors on the coils making a bigger problem.
