JIm,
Check the Temp sensor II first.
Mine did the same thing when cold.
Replaced that----solved.
The lid to the AFM comes off with the cutting around the edge with a
razor knife, and gently prying the lid with a wide edged screwdriver.
Take your time, it will come off.
My Van suffers an off idle problem, not a cold start problem. (anymore)

Later,
