I thought I had read somewhere that Ford was having issues with it's V10 popping spark plugs in a certain cylinder. I just experienced that problem on a recent road trip. The engine popped the (I'm not sure which cylinder it was now. Driver's side second to last cylinder) driving down the freeway it blew the spark plug out and broke the coil pack. I put in a new plug and replaced the coil and was able to finish driving home 1,000 miles.
You shouldn't worry but you should fix it. There are others with a lot of experience with this and if you do a search you will find a TON of data about this problem. The repair is not terribly hard but do a search and it will lay out the steps to take. I am sure others will chime in. Good luck.
If you were able to get the proper torque spec on the replaced plug you have nothing to worry about,
I had one spit out on a 5.4 v8 about 30k ago . It has 69k on it now
Its still going no problems

My low mileage 5.4 spits 3 plugs in 3 months. One at a time. Heli coiled one at a time. Towing, labor and coil packs cost me about $500 and I can't afford this problem stopping my business so I had the rest done. Seems like a common problem with this engine. Just ask a few repair shops as I have. Seems Ford should step up to the plate! 3-4 Alum. threads is not enough. The newer Heads (made in the last 2 years or so) are supposed to have 7-8 threads per hole. I can't afford the $7,000 new heads. Admin note: see our guidelines about law suits

Several of FTE members have used this product with excellent results. One member even outlined a complete step-by-step procedure to install it in a blown plug hole. Check the archieves. Looks simple to me, and for a few hundred bucks for the tools and devices you can save thousands in needless head change out.
