I'd take the spark plugs out and blow some air into those cylinders. Might have some crap in them if you said you found a bug in one the coil packs.

Is there a way to keep the sparkplugs from breaking?

5.4 has COP's. No plug wires for the big v8. Some times they dont seat correctly.

So I won't have problems with them snaping?

Carcrazygts2

nope.

What cops did you put in?? Also, I don't care how much you think you checked the connections.....check em again. If need be, disconnect them and reconnect them..make sure you hear the click of them engaging.

To many times have I seen people get fed up with it and take it to a shop and it turns out to be the connection.
