What are coil on plugs on the 1998 mercury marquis

SOURCE: where are the spark plugs located on a 2000 Mercury Grand Marquis

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.

SOURCE: Cigarette lighter doesn't work in my 1998 Mercury Grand Marquis

sounds like the lighter itself is bad because the fuse for the lighter is the same as the fuse for the connecter in which the inspection machine plugs in to.

SOURCE: I got code PO 305

I got code PO 305 on a 2002 Mercury Grand Marquis, what is the spark plug wire part called
This will have a direct coil over ignition with a coil over each spark plug. The coil is the electrical part over the spark plug. The coil also has a rubber part that is called the boot or spark plug boot. The boots can be purchased separately but the coils will come with new boots.

is it #5 coil,

Have you checked to see if there is any spark coming out of the number 5 coil?



and should I replace the coil and spark plug and what should the spark plug be gapped at?

When was the last time the spark plugs where changed? It may be due for all the spark plugs to be changed. The spark plug gap is usually listed on the emissions sticker under the hood. It should be .050 - .056 or very close to that.
