4kq sputter update & cold idle probs

[R Mangas]

   I think the cold start valve only opens when the starter is turning; if
you're getting good starts in colder weather (how cold?) but the idle is bad
that's a sign of poor afterstart enrichment.  Main driver for that is the
coolant temp sensor, which are cheap and should pretty much be replaced as a
matter of course.

  That's where I would start, that and a vacuum leak witch hunt.  Everything
else is tougher and more expensive.
