Hey people, so I ventured to Advance Auto parts today and got my car (Service Engine Soon) light checked out.. Heres' the read out, code #1:

P0440: Evap Emission Control System Malfunction

P1448: Manufacturer Control Auxiliary Emissions Control

I was told that one code was probably my gas cap not being on tight, but I checked that out, It's on as tight as it will go,maybe its time to invest in a new cap ?? And he told he didn't know about the other one. So that's why i'm bringing my information here... I thought there was a code analysis somewhere on the web, but I don't remember where. Any help would be greatly appreciated, and if this has been posted numerous times, i'm sorry forgive me for the repeat.
