I think OBD1 was for 89-96 and OBDII was for 96 and up...
I think thats the years for them, correct me if I am wrong. Its just what I think I remember hearing.

OK Then explain to me why my 95 which was stock when we bought it almost 10 years ago has 2 O2 sensors, in it & when we did the updated exhaste on it, we had to move the 2nd o2 sensor.

OK. Let me rephrase. OBD1 has one O2 sensor on each bank (meaning each side of the engine) and OBD2 has 2 on each side. OBD1 has one in front of the cat. OBD2 has one in front and one after the cat.

Earlier OBD1 (ala TPI and the old TBI) was all running on 1 o2. Not 1 o2 per bank.
