Hi,
I have a TA-85 with the LG4 engine. Does it have an O2 sensor? If so, what does it do? Does it control air/fuel mix on a carburated engine? I also wonder what the ECM does for my car?

The O2 sensor should be on the driver's side exhaust manifold, if equipped with a computer controlled q-jet. For some discussion of the carb and system try:

Note that many export models were not computer-controlled; only domestic ones.

The ECM controls the ignition timing and the fuel mixture; a few emissions-related components; and the torque converter lockup clutch, in automatic cars.
