i bought an OBD-II connector for figuring out wtf my care put on the check engine light and it's paid for itself many times. in relation to this, my brother's truck passes emissions fine but the check engine light comes on randomly. the connector can reset the "error code log" so i did that after his truck failed and it passed with no problem. the light came on later. the code that it was reporting was not helpful in the least... but it's an old truck so the sensors werent as elaborate and sophisticated as today.
oh, for all you that are interested in tweaking or just repairing your car get a OBD-II connector, you can see every detail about how your engine is running. you can buy the connector here:
