New Techinfo Topic - O2 sensors

A new Techinfo topic has been added to Specifications. 1987 to 1999 O2 sensor part numbers and prices. 2000-2003 data coming soon.

I need someone to tell me what year began using 2 sensors. I think it was 1996, but it might have been different for NA and SC. Let me know, and I'll add that info to the topic.

OBD II started in '96? I thought it was '94. Is the 1981->1993 system (the one where you jumper the A & B terminals together for a readout) considered to be OBD I?
