    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.

    code list
    p1518....p0851.....p1152....p1153........p0502.... ..p0503........p0442

    unplugged only the p0442 shows up, plugged in more codes show anything i should worry about?

    The green connectors should be unplugged unless you're flashing the car.

    Try tightening the gas cap, reset the ECU (to clear the code), and drive around to see if it comes back.
