Ok my 93 SE coupe is on its 3rd o2 sensor in 8 months. The codes are 1 and 43 like its been the times before. What could be causing this to happen? Id really like to fix this problem.

What brand is the O2 sensor?
It pretty well known that Bosche O2 sensors do not work well for cb7s

When you removed the other new sensors, were they fouled? All covered in black carbon? If your engine is running poorly, an o2 sensor can get fouled pretty quickly. As said, be sure to check your wiring. If the wiring has been spliced or damaged in some way, the resistance (and therefore the reading) of the o2 sensor may be off.
