02 sensor

If I eliminate the smog air pump, will the O2 sensor output be eronious?

Is the O2 sensor on a 1988 351 w/thermactor system different from other years?

Does the air injection being up stream of the O2 sensor affect the fuel air ratio in any big way?

If so, will substituting an O2 sensor from a newer model with no up stream air injection improve the communication between the O2 sensor and the eec?

Thanks,
Tenderdoot

it should be fine just try and see, o2 sensors make there own voltage and fluctuate depending on mixture thats how they work. at about 100,000 km they tend to be lazy and worn out (not able to read and react to mixture fast enough). so a new one can make a big difference in itself
