[Peugeot-L] idle speed possible vacuum leak

Well, today, I went to run some Power Foam http://www.amsoil.com/StoreFront/apf.aspx through my 505, to clean her out and test the product's effectiveness (I am a dealer). In the process, I learned that a Peugeot 505s with Bosch CIS will NOT run AT ALL with the air cleaner boot or anything plumbed to it disconencted. I managed to create temporary access for a small tube to run the Power Foam into the intake with the engine running.

I run her a little above idle, she takes it, and I shut her down for 10 minutes as prescribed.

After the soak, I fire her up, she smokes like hell, some from under the hood, too,near the exhaust manifold, which I thought strange. She runs fine. I reattach everything and start her again, she starts fine, I do some other things near the fuel tank, give up on conencting the fuel gauge, give up on changing the small fuel filter, in the process, discover the small, white plastic item that looks like it could be a fuel filter plumbed into the fuel tank is not a filter, but a check valve.

I go to start her again, no dice. What???

I manage to get her going by plugging the egr (I think) hose that goes into the air filter boot with a screwdriver. She now runs, but idles at like 2,500 RPM. Figuring the valve has not failed, but is just stuck, I reconnect it more tightly, and she starts, but still idles at like 2,500 RPM!! This the state she is in now, power is a little better, I installed the new spark plugs in an attempt to get her running, which did not help.

You guys weren't kidding when you said these thing are sensitive to vacuum leaks!

What the hell did I do? Did the Power Foam clean her up that much? I remember there is a ringt and wrong way to adjust the idle speed, which I will search for in this list.
