Hi,

Since you did not post that the idle is rough, I would assume that what you are referring to is that engine will not idle when cold. Areas/components to check would be (depends on the regional version of your engine):

1. auto throttle choke;
2. Air idle valve (electrical);
3. injector and injector pump (least likely).

try haynes.com or your local parts store for a Haynes manual.  For around $20 they are frequently as good or better for home mechanic than factory manuals for $100.
