It was getting through nearly double the amount of fuel it should. After no leaks were visible and there were no spots on the floor I decided to plug in my diagnostic equipment to look for trouble codes when I didnt find any I was bemused so I started testing systems through the diagnostic interface and low and behold it came up with the following: Evapourative fuel system leak !!! how can I find the location of this and how can I remedy it ? please help me !!!!!!!!!!!!!!!!!!!!!!!!
