Depends on what engine you have. You didn't say.

On the 4.2, cylinders 2 & 6 are on the same coil section.

That means that the coil is a possibility, however, blindly replacing the coil is has a fair chance of being a wasted effort.

Question

Also, Last week I had a header gasket replaced and I was running the truck for a while with a leaking header gasket. Could that have caused this problem?

I changed both coil paks and cleared out the codes yesterday, it helped alot but there is still a miss. I guess plugs are next on the list...
