'04 Cavalier Massive Evap Leak.?
I had my engine light come on, i went to auto zone and they scanned my car and got a error code that said Massive Leak in the Evap System. They convinced me it was probably a result of a worn gas cap... Thus I bought a new cap $10. The problem still persists.
I disconnected the battery to try to clear the ecm, did not work.
What are the possible leaks?
What does the leak mean?
How do I clear the error if I don't fix the leak?

a large evap is sometimes the gas cap but you have done this already,take it to a gm dealer and they will put it on a smoke machine,it fills the system up with smoke and if there's a leak it will show up,may cost a bit,or you might have to get a mechanic to use a scan tool to clear the code,dc the battery doesnt always work,hope that helps.
