Post Auxiliary Air Regulator (Why take the manifold off?)

So I'm sitting there, starting to loosen the alen bolts on the throttle body, then it suddenly struck me, WHY take off the manifold? Why remove the aux. air valve at all? Why not just spray carb cleaner on the intake side? Isn't that all I can do when I take it out anyway (if not replacing, which I'm not).

Well, I'll do this either tonight, if it doesn't help, I may remove the thing, and totally soak it with some type of cleaner/lubricant, we'll see, but I think it'll be OK.

Keep us update on this topic, my aux. valve is also in need of some attention and I would be happy if I don't need to remove the manifold.

porscheboi928s/c944t/n, I doubt there's any chunks of carbon build up, that'll work it's way loose from the aux. air valve, into the chamber. (Keep in mind, the aux. valve never gets as hot as the combustion chamber, any deposits are likely to be moist, and soft).

Anyway, since I'm pulling the air flow meter, and thinking about a funky ram air, I think I'll go ahead and pull the manifold. This'll let me soak the aux. air valve with carb cleaner, from both sides.

PS: Decided to do this, since if the valve is stuck closed, none of the carb cleaner would go through it.

Ahmet, if your AAV is semi-healthy and only needs cleaning, then spraying from inside should be fine. However, you will never know if it is in good condition unless you take it out and test it, by running some current through it to make it close, and/or putting it in a freezer to make it open.
The main thing that helped me when I took it out is to adjust the opening by repositioning the plate with the small nut on the outside.
Good luck.

Sorry, my PC froze, so I pressed the 'post reply' button a bunch of times, and I guess the server just accepted all my repeated requests later ...
I apologize again.

The part numbers for differ from year-to-year. My 86 944na shows "Idle Stabilizer" PN 930-606-161-00. Any difference in function from the earlier units? The list price of a new one is $148, with Hendrick's selling it for $104 - so I'm hoping to clean it up. What a pain to remove... remove fuel rail and intake manifold.

I think the later units are more precise, but not positive. I know they have different # of wires going in to the valve however.

I'm not going to have time to do this soon, like I planned. I have to do my brakes, wheel bearings, get an alignment, change transaxle fluid, fix coolant leak, etc.
