Every time I fill up with a full tank, my LTFT numbers go from near 0 to -22. This lasts for a few minutes, or until the next time I start the car. Anyone know why this happens? Good news is, things do go back to normal eventually. Thoughts?

Could be the colder, denser fuel as it comes out of the ground. The liquid eventually comes up to ambient temp and functions normally.
