Hey guys,
My check engine light keeps coming on and when I check it with my scan tool it is P0440 evap emission system. I replaced the gas cap and as far as I can tell don't have any leaks. Any suggestions? I don't have a smoke tester but would like to check myself so I don't have to pay to have it done. Thanks in advance.
