I have an 89 Toyota Van in addition to my 4th Gen 4Runner

What would cause a random misfire that jumps around cylinders only when the engine is cold? When the engine heats to normal temps the misfire goes away and I have normal power. I have ruled out the EFI system as the cause. In the area of the igntition system what would cause this behavior?
