I have a 2005 Lincoln LS V8 and have 8 coils, one per cylinder. Your car being a V6 should only have 6. Never-the-less, I have had multiple go out. There is a 100,000 mile factory warranty on that part. I had a ford dealership make me aware of that when I was facing an estimate of 1200.00 to fix 3 that went out (they were saying $350. a coil). I am now over a 100,000 miles and had a couple more go out. Here's what to do, find out your part number for the coils and search on ebay. I bought 4 for something like $16.50, took it to a local mechanic and had him put in for 100 bucks. I watched him do it, it is very easy because each coil is located on top of each cylinder so all it takes it taking apart the framing top portion and inserting each coil in.
