I am thinking coil pack as well. Is there a way to test them ? I bought new plugs to start because it is over due for them.

That does suck. But that's the way it goes with mechanical things sometimes. My Chevy is a 5.3 and has plug wires (though short ones). I ASSume the 6.0 is similar or the same.

Spark should be clear and evident. If not, there's your problem cylinder. Word to the wise - do not hold the screwdriver while testing. Or have some unsuspecting helper hold it. A good time will be had by all.
