bad 02??

I have a 94 t-bird. The car sputters and has power surges. I ran the codes and found that there is no voltage in the 1st o2. So i put in two new 02 sensors but i am still having the same problem. so i ran the codes again and there is still no siginal from the 1st o2 sensor. I am thinking that the wiring from the o2 sensor to the pcm might be bad. any thoughts???

thats a possibility i think. check for any frayed wires or loos connections. you may have even been sold a bad o2 sensor.
