Quit shotgunning. You'll spend more on wasted parts than if you scanned it to begin with. Have you thought about the possibility that we may have a member with a scantool nearby?
Correct, 95 only has one O2 sensor....
This car will have to be scanned with a scantool capeable of reading 1995 GM cars, with a 16 pin OBD2 cable... Its is OBD1, but uses OBD2 codes and connector...
Like it was said, these are all guesses... Keep guessing and you'll be throwing your money out the window
