I had some sketchy idle problems the other day, after a can of seafoam I threw in the towel and decided on cleaning out the ICV, or as the Bentley bible calls it the "Air Stabilizer Valve". So Off to Autozone I went, Here's what you will need/What I used:
***All pics below text for easier reading of DIY***
First things first, I went into the project with Bentley in hand. Here's the thing your going to be removing and cleaning. The Bentley didn't go into much detail so I figured why not make a DIY while I'm at it.
First thing your going to want to take off is the electrical connection. It's sorta hidden but not hard to find, pull up on the two tabs and then pull the connector off.
Now you will see the two hose clamps that will need to be taken off. I found it easier to take off the piece that mounts the ICV to the engine to help be able to move the ICV easier to get out of the hoses. The far clamp came off no effort and the factory crimp clamp was a bitch, so thats where the Wire cutters come in, just hack the thing off.
After realizing I didn't have the right size hose clamp I jumped in the Turbo and off to Autozone again I went. The digital calipers read about 1.4" for the hose diameter so try to find a clamp that is 1.5".
After getting back and making sure the hose clamp fits you now can get on to the cleaning. You will notice there is an intake from the intake boot and the exhaust part of the valve that points parallel to the engine when mounted. I took my spray and carefully and slowly allowed the cleaner to barely squirt out of the included spray nozzle and let it just drop out of the bottom hole*See picture for this to make complete sense*
Now put some engine degreaser on a rag and rub the outside of the ICV to make it all nice and half-shiny looking. Why not clean the outside too?
Let it dry for about an hour (Take a nap, oder some pizza and a drink of your choice, the hardest part is over) before installing back on the intake. I let my car sit for another 6 hours before I started it back up and drove it around the block. Installation is the reverse of disassembly.
Below is my parts getter when the e30 is down. S60 Turbo FTW.
The hardest part is done! Now to wait and eat.......
- Carb Cleaner
- Engine Degreaser
- Flashlight(depending on where your working)
- Wire Cutters
- An appropriately sized hose clamp
- Q-Tips
- #10 wrench for getting the ICV mount off
- 5/16" sized wrench to clamp the hose clamp

those factory clamps are actually a standard for use in irrigation work and can be used any funny pipe/rubber hose.
when I do repair work on any hoses or pipes when working irrigation, the EASIEST way to get those clamps off is to grab where you can see where it was crimped inwards and twist. It should snap easily, and if it doesn't give it one or two more twists....Cutting them is actually harder.
Depending on the icv, if it has a metal shroud/inlet then your safe in doing this. If its plastic, I am unsure, I would recommend cutting and not possibly over tightening the clamp to the point you crack or break the icv
using them when twisting off makes it super easy
