cold start-ups? how cold actually? i'm wondering if you have any sort of clogs (ie: PCV valve, IACV, do our engines have a FIT valve? -- i'm new to Subaru, catalytic converter -- must be hot to function properly).
on my dad's 79(?) Benz 230, it had problems staying on due to a clogged muffler. after sawing the exhaust piping, it stays on fine. running smooth is another story.
any vacuum leaks? this can make it difficult for the IACV (in relation to the ECM) to function correctly.
on a JDM B16A engine (in a 95 Civic Si) with a vacuum leak, my engine would slow die off. this was usually during the first starts of the day. when the IACV finally went bad, the car would buck (or have a real bad idle in neutral) and would quickly die.
if you do the sea foam stuff, make sure any internal gaskets (rubber-types) aren't too worn.
