so my CEL came on took it to autozone got the code pulled out which is P0442 Evaporative emission control system malfunction? guy saids maybe gas cap or a vac hose loose or cracked okay. while messing around in the parkin lot i come across a green connector unplugged Which is a diagnostics mode or sumting which i read about. well i plugged it in and the cel began flashin so i told to the dude to check it again he pulled 7 codes this time. then i unplugged it.
unplugged only the p0442 shows up, plugged in more codes show anything i should worry about?
