    nope.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    are you getting any codes or have you gotten any recently? I have had mine triped by the MAF code in the past. I am not really sure about the details on that one, I think that one is set for non emission codes if I am not mistaken, but I am not 100% sure

    i did have the MAF codes, but the Service Vehicle light has never come on before...maybe the light is set to illuminate after several cycles with the same coded SES light

    Service Vehicle Soon light is a non powertrain fault. Drls inop, RKE malfunction, stuff like that. You need to find out what the code is. Also what Y/M/M is the vehicle?
