OK My Idle jumps from about 750-2000 rpms. I was told by the dealership it wasthe IACV. I replaced it and it still does it. They said something about an idle run in procedure.. They also told me it was in the shop manual, I can't find it. Any ideas what this is and how to do it?

FYI the only time the car doesn't due it is if the outside are is hot and the car has warmed up or if the car is moving above 25mph. Above 25mph and push the clutch in and let the idle drop to idle speed it stays steady till I get to about 25. Any input would be a help. I really don't want to get raped by the dealership again.
