that is crazy. here is the process and it can be done in less than an hour....

pull battery negative just to be sure...

get a 1/4" 7mm swivel socket and about 18" in total extensions. Get a universal joint for you spark plug socket (make sure it has the rubber insert to hold the plug in place). You'll need a short extension on the plug socket between the universal and the socket. You'll then need about 18" or so of exentions to make it easy to reach back there... You also MUST have one of those long thing magnet tools that is like a long car antenna.

ok, you have the tools.

there is NO need to remove fuel rails, TB, etc.

Reach down and unplug each coilpack. There is a small squeeze clip on bottom... pull all eight.

Also, unplug the gray injector plugs on each size as they are in the way of the 7mm coil pack screws. Those must be squeezed from the sides to be removed. You can also pull the small twin vacuum lines on the driver side to make it easier to reach, but not necessary...

Now, take the 7mm swivel assembly and loosen each coil pack screw. Just leave it in the hole once loose. Loosen all eight right then. *Use your magnet* to remove them from the vehicle. The driver and passenger side rears have a pretty nasy angle, but the swivel socket will reach just fine.

Next, pull all 8 coil packs out of their sockets. The front driverside will have to come forward of the Intake tube...

Now use the spark plug socket to remove all 8 at once. The passenger side rear will be tough to get the socket well seated so you will have to "play" with it, but that is the only one that will be tough.

Once you have out all 8, put your new plugs in the socket one at a time and lower them gently into the sockets without banging the tip and therefore closing the gap.

Tighten each plug until snug and then give it maybe 1/16th to tighten. If you go too tight, you'll strip it. Too loose and you blow a plug later...

slip all coilpacks back on. Hand insert 6 of 8 coil pack screws. The rear two on the driver side will need to be inserted using the magnet. I would advise, if you have thin hands like I do, to try to hand tighten these two once seated so you don't cross thread them. Snug these down with the socket and give them a small turn. They strip easy.

Plug injectors and coil packs back in. Make sure you didn't knock vacuum lines loose on drivers side (or reconnect if you intentionally removed them)...

start it and check for idle.

I got it down to 20 mins per side by the time the day was done. I suspect on a cool motor, with no distractions, I could knock it out 15 mins on passenger and 20 on driver.
