    Bradley:

    With the car OFF, just hook up the 9100 to the OBDII port under the dash and the 9100 will prompt you with directions for reading the codes...it's that simple.

    Let me know what code(s) you get and I'll tell you what they mean...

    The MAF connector is tight!Should I disconnect the battery?I did install a RAI (JLT)recently.The light came on just befor the Dyno friday at the time the lamp came on It had the factory air box installed.I did notice a small thread on the little device that hangs into the Maf so I delicatly fished it out.I thought it would interfer with the reading.I don't know if it is related at all?

    Without going through the troubleshoot, which could lead to several conclusions, P0102 looks like a bad MAF. But, we'll see what the dealer says..
