We have a 1993 Eagle Vision, 150k miles. We need to get current tags, but the car will not pass emissions. We have changed out spark plugs and wires, oil change, air filter, gas cap, misc other.... When my husband went to change out oxygen sensors (supposed to be four of them), he said there isn't any. He (my husband) thinks that it might possibly have been a Canadian car, but... ? Is this for reals? How can an emission system not have any oxygen sensors?
Answer to question below... Car has original engine.
