I suggest you also check the PCV valve hose ( or any other vacuum hose you
can find). I just changed my PCV valve. I tried running idle the engine with
the hose off: the engine slows down gradually untill it stops completely.
This description is similar to your symptom.
I also had a 1988 626 before . Once the air bellow had a small leak, causing
erratic idling, and engine hesitation when starting from stop untill
reached second gear speed (manual ***). I used the electric tape method
to seal the leak - lasted for years !!
