Need Help...
I've looked at so much crap...but I can't seem to solve my problem.
I have a '91 200 20v, and the engine is in pretty good shape. But whenever I'm on the gas, and then clutch it completely, the RPMs drop down until the car just dies. It does it in every gear too, but most noticeably second. For example, if I'm turning left onto a street, and the streetlight is close enough to stay in second, and I need to clutch it to stop quickly, it dies.
I've cleaned ISV, no vacuum leaks, manifolds are OK, all hoses in correctly. Could it be the air filter? Any help is greatly appreciated.

Yes it's mounted to the turbo inlet hose. A new one is $30-60

No the stock one isn't serviceable.
Carb cleaner would likely dry out the diaphragm.
You can test it with a mity vac to see if holds vacuum via the nipple on the bpv. If you don't have a mity vac you can remove the valve and push the diaphragm spring open and put a finger over the nipple to see it stays open, kinda like water in a straw.
