I had this problem for a while.  I came across a parts van and tried
swapping the idle stabilizer valve, and the cold idling problem went away.
Now the idle speed just bobs up and down just slightly, but it always
idles when cold.

By the way, in my limited experience, even the part that you think is good
can sometimes be the source of the problem.  At least a couple of good
mechanics told me that the problem as described was not caused by the idle
stabilizer valve.

HOpe this help,

2 '87s, and still trying to figure out which one to sell after a year
