I decided to change the coils on my 6.0. It had orginal round coils on it. I took the square coils off a 5.3 i have sitting in a 99.

Reason for change. I am trying to figure out why iy ideals fine when i first start it. But has a miss when i get to toen. Which is maybe 3 miles from home.

Neighbor suggested a coil going bad. But. Still going it after coil swap and wire swap.

Could a plug be going bad once it warms up? Or could it be an injector?

Slight stump on my end here. Not sure which way to go. I do plan on getting new plugs and wires once i get paid. Just trying to make the truck run a bit better for now.
