Question about 2003 Lincoln LS
Remove the coil covers on top of the valve covers-to get to the COP-Ignition Coils. I believe you need a 7mm socket and 7mm small wrench. You need a PO301 to PO308 code- for a bad coil. Their about $60.00 at auto part store. Just do the one that fails.
Cylinder #1 is front of vehicle/pass side. 1 thru 3or4
Cylinder #4or5 to 6or8 on driver side.

SOURCE: which ignition coil is bad?
I went thru this on my 2002 LS as well.
I replaced one ignition coil at the dealer - only to get the same misfire code on another cylinder. After a little research found out is actuall a gasket/o-ring problem design of the block. Spark plugs are deep in the block - under the oil - which is why they are supposed to last 100,000 miles. But the o-rings start to leak some where between 65k-85k miles. Coils go bad because of oil contamination. If you don't solve leaking oil problem will have to replace coils again - but sooner - because leaking oil will be progressively worse.
Cost - 8 ignition coils
set of spark plugs (who knew they were that expensive
and a ton of cash for the labor to tear down the top of the motor

have you considered buying a $14.oo haynes repair manual from Kargen or one of those type stores? If not just google your year, model and engine type and a diagram comes up

The spark plugs in the v6 can become an involved job as the upper intake manifold. The LS uses a Coil on Plug (COP) ignition system, meaning that the spark plugs are located under the ignition coil
