So i have been following the drive cycle for my 08 ls panel and im now on drive #17(doing this 1 drive a day for over 2 weeks) and still no evap yet... I have everything else however for some reason evap just doesn't want to set... The car isn't registered or inspected so i have to do these drive in the middle of the night... however i have been doing the 15mph stop and go driving for 5-10 mins... then i bring it out into the country side and do some 45-65Mph driving for a good 10-15Miles each night... i then get home park it and no one touches it until the next nights drive... What am i doing wrong here?? I have no CEL no pending codes nothing.. its happy as a bug in a rug but will not set Evap... I need this car legal by April 6 so any help yall could give would be greatly applicated

 

According to this it takes 18 or more drive cycles
