Barton, For #2 - my guess would be to go with the fast idle. Part of
my reason is to keep the engine from "strugglling" which it will do
sometimes when it is cold. I feel that the slightly higher RPM helps
the oil pump build up pressure better. Also, MB wants us to - that
is why they provided a fast idle. Bobby
