I have a check engine light with code P0456 (Evaporative Emissions System - Small leak detected).
I replaced the gas cap and cleared the code, but the CEL came back after couple of days. Next step is to take it to a mechanic and have them hook up a smoke machine to find the leak, but this is going to cost me. My next emission test in in about a year. Can I keep driving the car for while(1 year) as I have not noticed any decrease in performance or fuel economy?
Will this make the "leak" worse or damage any other components?
