I have been trying to troubleshoot this for about a week or so now and I am puzzled and need some advice: I am getting a CEL 90 which is a EVAP code(possible leak in fuel system) . I made sure that my gas cap is tight and at first found a small leak and got that fix so its not leaking anymore. I will reset the code and it will eventually come back on in couple days... I cant figure what else is causing this so any help is appreciated...
thanks

 

bump...need some help..

 

do you have any idea what the code is with a scan tool? if so I can get you some
diagnostic information. Does it say if it is a small evap leak or a large one? I would assume since it takes a few days for the code to come back that it is a small one. Those are the toughest to find, you may end up needing to take it to a shop that has a smoke maching to find the leak, anyway if you can get the scan tool code, should read something like p0400 something like that I can give you a hand figuring this out

 

thanks i will try to get a scan tool this weekend..I will keep you in touch..thanks
