How long has it been since you changed your O2 sensor? Sometimes, as they start to go bad it will cause the light to kick on, particularly when you are at higher RPM or under a load.

The guy at autozone has never seen an OBD I plug? I guess that makes sense. They probably have an OBD I scanner in the place for like $40 but they're too dumb to know what it is.

Old post but I will bring it back if it helps anybody...

Reading the Codes
1.Locate the ECU (under your dash in the center) and look for a small screw next to a LED (towards the back end).
2.Turn the ignition to the ON position (engine not running).
3.Turn the screw fully clockwise, wait 2 seconds, and then turn it fully counter-clockwise.
4.The LED will start to display the code by a series of long flashes, followed by a series of short flashes. Your check engine light on the instrument cluster will also flash in the same sequence. This sequence will repeat.

1 1 Crank angle sensor/circuit
1 2 Mass airflow sensor/circuit
