EVAP system code-I'm being taken for a ride
 

Help My 2001 Sonata check engine light came on and the codes came back for
EVAP system leak small and large. I've had mechanics tell me the fuel
filter needed to be changed (which I did) and that spark plugs need to be
changed also, as well as air filter and about anythign else they can come
up with. Do any of these have anything to do with the EVAP system. Car
will give a little lurch when driving it and then not accelerate well and
feel sluggish to drive. I get different stories from every place I take
it and am desperate for some info from anyone who can help as money is
tight and I don't have cash for extraneous repairs!
