This isn't as good as SL1CKs, but it is for the 2000+ which is quite simpler!

It also shows the IAC valve, which is so easy to take out and clean, but so expensive to replace!

Behold... my clean engine bay. It's more fun to work on a clean engine. I like to keep it clean!

To remove the air intake duct, simply unscrew the two screws on the air filter housing, and

unscrew the slotted bolt holding the intake to the TB.

Here is the IAC plug, two phillips screws hold it in.

When you take it out (After unplugging it) here is the port hole, clean this well too.

Here is the IAC valve, and it's two fastening screws. I cleaned it with electric parts cleaner, so if any of the solvent leaks into the electric motor or windings, it doesn't harm them as it's non-conducive.

This is a dirty IAC valve. The shaft is supposed to be shiny metal, not black soot.

Remove the duct work (unplug MAF sensor plug first)

Dirty TB

Spray it with the TB cleaner. I use a Toothbrush as well.

After the cleaning, the edges are clean and the back of the throttle plate (WOT, shown here) should be clean, as well as the mating area with the TB. Don't worry about the stuff further in, that'll dirty up in no time and does not affect operation.

The heroes of the tale! The electric parts cleaner saved my EGR valve on the Eldorado ETC I owned... u can use regular TB cleaner, but allegedly if you get the electronic windings wet with it, it can become toast! I used the Electric parts cleaner on the $349 retail price IAC.

Your instructions are just what I have been looking for. Can you repost the pictures?
Thanks,
Tim

the pics are live, try refreshing?

With exceptions for the surge tank and airbox configurations this is good for the whole 2000+ Seville/Deville series. Nice work.

Great tutorial... I would add one warning to the handling of the IAC valve. Don't attempt to move the plunger in and out... it can damage the threads on the worm drive.
