    Truck is running rough, feel like "bucking" or trouble shifting

    So what have you done to it are going to do to it Maybe time for some maintenance like new plugs fuel filter check for vacuum leaks

    You need to provide better details other than saying "Truck is running rough"

    I'm working on it. Plugs have 60K Hwy miles on them, same with fuel filter. When I had the tuneup before, I replaced the #3 coil pack. Looks like I'm ready for more of the same. I now understand this "coil pack" issue can be a source of the problem. Now, I just have to decide whether I go to the dealer or not

    If you have a CEL have the codes read and post them and if your just replacing plugs make sure you replace the boots also.

    Glad you figured it out When you install new boots use some dielectric grease on the inside of the boot
    Also make sure you torque the plugs to the proper spec
