Hey guys I have a 2002 Toyota echo that's giving off the usual emissions engine codes,I suspect a lot of it may be caused by a fuel leak. I'm pretty good at working on cars but don't know much about emissions and fuel related stuff. Anyways I'm not seeing any visual signs but I notice when I fill the tank I smell fuel also think if the evap is working proper it may not vent proper . I will grab the codes again tomorrow and update as that may help someone be able to possibly point me in the right direction.
