Truck violently shaking?

I recently started getting a check engine light for misfires so I went to check the spark plugs and found one that was cracked in the ceramic part. After replacing it and starting the truck, it has been shaking violently and sounding like it wants to stall. I haven't tried to drive it anywhere due to that. What could be the problem. I'm not getting any codes yet, could a piece of ceramic from the plug have fallen into the cylinder causing this? I have a 2008 Ford F-150 5.4L V8. As far as I can tell I didn't do anything wrong. I'm really wanting to avoid going to a mechanic and have him charge me a fortune for random things

Check to make sure you have fitted the plug leads back in the right order as misplaced leads will cause this. Although I have no experience on a F-150 V8 I believe the firing order on this engine is 1-3-7-2-6-5-4-8.
Hope this helps.

You replaced a Spark Plug and now it runs WORSE. Doesn't that tell you something? Remove the new plug and look at it and check the gap. OR replace it. Also make sure you didn't bump a Vacuum Line off it's fitting.

Did you set the correct spark plug gap? They often come out of the box with the incorrect spark gap because one plug type is often used on many different engines that have different gap settings. It's a common mistake to assume the gap set at the factory is the correct one.

Did you make sure all the spark plug leads were put back correctly? That's another common error.

A piece of ceramic couldn't have gotten inside the cylinder if the insulator was only cracked. If you broke the insulator when removing the plug and you weren't careful then maybe a piece fell down inside but it would only cause roughness if it was exactly the right size to get caught under an open intake or exhaust valve. The only way to check for that is with a bore scope.
