After scanning a 99 Nissan Pathfinder SE, 3.3L 4x4, I have some questions. Using an OTC Encore scan tool, there were two Engine codes---71, which is a Random Misfire and 3F. I cannot find anywhere on the Internet or even OTC what 3F means. Obviously, the vehicle is not really OBD2 compliant and although the tachometer worked, the RPM and another item called something perhaps like Mass Air Flow Sensor voltage were shown as 0.

Does anyone have any comments that may help?

Thanks

The 99 is fully OBD2 compliant. The OBD2 code for a random misfire would be 300 and any error code will come back as three digits, not two. I would would try another scan tool; probably one of those generic, ELM327-based adapters that interfaces with a smart phone.
