thank you for all that info, but what I meant was how many miles do you have to drive before the computer learns your driving habits, and makes adjustments accordingly. thanks 2006 LS

don't bother....take it to a shop with a smoke machine. unless you want to throw parts at it until your blue in the gills. You could have a pinhole leak in any of the evap components and set this code. You would neevr see it with the naked eye. You need to have a smoke machine hooked up to it, and have the system pressurized with smoke and wait for the smoke to come out of the leak
