So i did some digging today without actually getting under the car. I'm not sure what to look for to determine OBDII vs OBDI harness, but I did pull codes for the car. The OBD plug was under the dash, next to the hood latch lever. I've done a bit of searching and I think that if my car was setup as OBDI, I wouldn't have that port.

Here are the codes that I pulled:
P0125 Insufficient Coolant Temperature for Closed Loop Fuel Control
P0173 Fuel Trim (think this is bank 2)
P1186 O2 Sensor Heater Control Circuit (Bank 1 Sensor 2)
P1188 Fuel Control (Bank 1 Sensor 1)
P1189 Fuel Control (Bank 2 Sensor 1)

This is definitely pointing to faulty or missing O2 sensors. I'm guessing that I'm in for 4 new sensors.

I'm still curious to know if I need to run 2, or if I can get away with running a single after-cat O2 sensor

I also have concerns over the I/M readings from the tools. The following were in a Not Ready status:

Cat - expected since it's nonexistent Evap - not sure what this is about
2Air - i think this may have been removed from the car
O2S - somewhat expected
HO2S - somewhat expected

Looks like I have quite a bit of investment and work ahead to get this car to pass emissions. Any experience in this area is appreciated.
