The 02 Crown Vic's do not have "plug wires". There is a coil attached to the top of each spark plug. look for 4 identical "boxes" along each side of the motor and those are the coils. You unbolt those to access the spark plugs.

This is a common problem your having. These coil over plug boots are recommended to be changed around every 100k miles. They can go longer, but then only one failed coil can cause this kind of problem. They are located on top of the engine under the fuel rail and in between the fuel injectors. There is one for each cylinder and each has its own wire connection. First off, shut engine off. Then you can check their connections to make sure the connection clips are locked on and that the small bolt holding the actual boot on is tight. Lightly pull on the housing of the connectors to make sure they are snapped on and locked. If none are broken or loose, and problem remains, plan to replace all of them. There are ways to check the resistance and also you can buy a spark check tool to try to single out the actual faulty one, but who wants to do all that right? By the time you check out all of them one at a time, if you even know the resistance parameters, you could have taken the advice of the owners manual recommendation to go ahead and replace all of them and be done with it. So with that said, get you a bit driver set cause this will work best, small flat head screwdriver, a socket set to remove your plugs, a grease rag and some latex gloves if you have them and a cold drink. Find the closest easiest one to get to first, go ahead and get you a bit driver out and loosen the set screw that holds the coil boot down. Get a small flat head screwdriver to depress the plastic locking tab on the underside of the wire connection housing. To remove the coil boot, just wiggle it out from under the fuel rail and pull upwards. Sometimes the rubber boot will pop off, but they are made to do this. If it happens, just get some needle nose pliers and grasp the boot to pull it up and out. It would be a great time to access your plugs to check for plug gap or replace them as well. Once you have done the easiest one first you will know how to do the others that may be harder to get to. Drivers side will most likely need the air intake box hose removed so you can get to those much easier. Two clamps hold this on and your bit driver can get that out of the way pretty quick. Now you can either take a coil pack down to the local auto parts place to match them up or order them online using the part number. Be sure you match up the coil pack connection housing. Some are different even though the actual coil looks similar. Also some of the rubber boots can have straight or angled boots. If you or someone else has broken the plastic housing connection on the harness, these can be bought also and replaced. Shop around online and check for prices, but remember a lot of times you get what you pay for. Lots of parts made in China are just exactly what you expect, cheaply made and unreliable. So if you have another vehicle to drive, go ahead and pull all the old ones out that way you can just install the new ones when they get there. Pick up some dielectric grease to dab on the connections and the end of the boot that contacts the spark plug. Coil pack goes down the hole, sometimes they snap on the top of the plug and sometimes they don't. Replace the set screw tightly without cross threading it, just enough so that the pack is firmly seated and doesn't wiggle, and then slide the wire connection on until it snaps and will not slide back off. Repeat this for all cylinders. Ive included a video that is not me, but it is good quality and will help you to see more plainly how to get these things out. This is a pretty much a guaranteed fixya.

Poor acceleration and running rough


Depends. A lot of bad gas out there with alcohol in it and it is bad for the bigger engines. Especially, aluminum heads. I blew a gasket in my Olds in May because of this and bought a Crown Vic Police Interceptor to end this problem with cars. The only way to find out if it is a plug is to do the engine test of unplugging one spark plug wire at a time. Not while running though as the shock is a "****." Do one at a time and start until you do each one to see if one or another is acting up.

You should pull that plug out and check it's condition carefully. Also that spark plug wire may be broken internally. Try a new or different spark plug and spark plug wire first and see if that helps.

Trying to locate spark plugs on 99 crown vic police interceptor engine


They should be mounted down in the cylinder heads, you'll need to remove each coil pack. A long extension and 5/8in spark plug socket and an extendable magnet will help. Also, you may need to remove the fuel rail to get to move the coil packs.
