 | | Subject: Fill up, LTFTs super rich. What's up? Sun Oct 14, 2007 1:16 pm | |
| 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.

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