I'm a complete "newbie" to my cougar, but I know that in its 56k mile life its never had its plugs or wires replaced and would like todo so. Can someone provide a good guide with pics on how todo this? Preferably by taking off the UIM and explanations on how to clean the UIM and so on... Thanks

Check the FAQ in this section for removing the UIM. It's not necessary, but does make changing the plugs a bit easier. Also you could give it a good cleaning while its out. Plugs and wires are a straightforward install, just don't mix up the wires and you'll be fine.

What is involved with cleaning it? Also, what are good wires and plugs to get as a "performance" upgrade?

To change the plugs, you need to removal the coil pack and the IMRC. The coil pack is towards the windshield and the IMRC box is underneath the duratec cover. With those two removed, you can see where the plugs are.

It is not necessary to remove anything to change the plugs, except take the plastic engine cover off.

it is a pain. I must admit that my UIM was off when I changed the plugs too, but only because i was doing an SVT swap :)

i have no problem getting the plugs out with the coil pack in, on my 2000 (using proper length extensions)

why do you feel you need to change plugs and wires with so low miles anyway?????

you would better be served by inspecting the plugs, and if they are ok, regap and reinstall them. if the wires arent causing a miss, why spend the $100????

i tried searching whem i originally posted, never found it. All you basically have to do is remove the plastic engine cover, and IMRC. And unplug the big plug going into the coil pack. Spark plug wires take 1 minute. The replacements you buy are already cut to length and have the number on it (1-6) which corralates(spelling) to which spark plug that goes too... Just replace one wire at a time, while replacing that wire inbetween replace the spark plug. To remove the spark plug, just need 12" of extensions and a spark plug socket, which is a normal deep well socket with a rubber ring inside to "grip" onto the plug when you move it out

All tools needed:
3/8" ratchet
2 6" extensions
1 spark plug socket
1 10mm socket (for engine cover and IMRC)
6 spark plugs
spark plug wires
spark plug gapping tool

Some spark plugs you buy come pre gapped. I do not think the autolite double plat do, so you will have to gap them yourself, really easy. When i first changed my plugs, i was a total beginner and noob, and took me half an hour. I can now change them in 15 mins flat.

I swapped plugs and wires on a MC NECO member's car when she was in PHX last year. I'd never done it before, and it was a piece of cake. No removing the UIM, no removing coil packs. Took me about 30 minutes or so. The most important tools are two (2) 6" extensions for the ratchet. With that, you can reach the back plugs w/o a problem.
