2010 5.4 missfire

I have a 2010 F250 with a 5.4. Truck has 32,000 miles and i am getting a missfire out of 2,3,4. Rough idle and gets worse as truck warms up.

I had the same issue once and was bad coil #1, changed coil and plug, done. but by all means if you are still under warranty, let the dealer take care of it.

Just let the dealer fix it. That is what warranties are for.

i second that! NO way i would still have a warrenty and try to fix plugs on these gas trucks. Plugs built with three pieces that pull apart and stay in the block, 100 dollar tool to remove it. Let Ford fix it!

Found problem

The converter is clogged. It now becomes the dealer problem. Converters are covered up to 80k and or 10 years, fed law. Ford has a recall on the issue. Thanks for everyones input.
