all i know is i got a lean evap code in bank 1 i had this problem for a while. i got emissions coming up and last time all i did was unplug my battery and drive like 10 miles for three days and i passed. This time i want to just fix that problem. i had my hoses checked twice, no leaks... and my gas cap is fine, i even got a new one.. everything seems fine. if anyone got some info for me that would be great! thanks!
