Is there some trick to putting this thing on? This is the second time removing it from my son's '00 4.0 and both times I have gotten miss fires. Cylinders 5 and 6 currently. Seems straight forward, snap in place and snug bolts. Am I missing somee?
I can only offer that when I have had misfires after reinstalling my coil rail, I had missed getting all six boots properly seated over the spark plugs. It is easy to miss a spark plug or two, especially in a dark garage.
