Hi,
I am totally new to this forum and hope to find good help. thanks in avacnce.

My good old Audi 2.3L 1991 with only 125 K miles (I am the second owner) runs like a charm but is very difficult to start and does not keep idle till hot.
There are new spark plugs but the problem seems to be a missing part near the throttle tlinkage and some kind of vacuum device linked to the distributor.
I have attached a picture of where I think there is "something" missing.

Your kind help is most welcomed

Thanks

Claude
