This is what it is.

If I were a betting man I would put all my money on the coilpack for that cylinder. Your valve cover seal is more than likely leaking oil into your spark plug well and shorting out the coil pack. It already has or WILL happen to all lincoln ls's that have the old style seals in them. New coil packs are $35.00 from autozone and your gaskel seal kit is $44.00 dollars from your local stealership

And if it has been raining don't be surprised if you have water in there and not oil but it could be just a bad coil if you've never changed any before

Is your car still under warranty - if so let the dealer handle it

Unless he has an extended warranty, his car's warranty is long gone.

4 Years / 50K miles, whichever comes first.
