Your unmetered air hunch could very well be correct. What year 930 engine are you dealing with here? I'm not familiar with the later models, but earlier models like '78-'79 had an EGR system that plumbed directly into the manifold way in the back behind everything and sort of underneath the CIS airflow meter housing. Often times the EGR system is removed and the hole in the manifold is "plugged" with something. A shop did this to my car, and their crappy plug job failed and my car would not run at all due to the massive intake leak. By massive, were talking a hole about the size of a dime in the manifold. Like you, I could make the car run by manipulating that metering plate by hand. This spot is hard to inspect with the engine in the car but with mirrors and groping around its possible to check. Its a less obvious spot where you may have an intake leak.

Best picture I have of where this spot is (see circled area):

Have my engine out, so took a picture of the EGR hole jwasbury has circeled out
This hole should be blocked
