Evap Leak Code

I have been fighting this for over a year. I get the CEL and I have had all 3 codes, small, medium, and large evap leaks. I have checked what I can with the scematics that have been posted here, but I cannot find the problem. Everytime the CEL comes on I reset it by disconnecting the battery and holding the positive cable on the negative terminal and then all is good for a while, but then it always comes back. What else should I do? Do I need to take it to the dealer and have them do a smoke test on it to find the leak? Any and all help will be appreciated. Thanks, Scooby

check the fuel lines going from the fill hole to the tank , make sure they are good and clamps are tight... and as strange as it sounds replace your gas cap. they are not that much less than 10 bucks.

buddy had the same problem the gas cap didn't have a good seal.

hopefully its the same with yours.
