1995 blazer v6 vortec with obd2 computer i beleive it is a 95 3/4
i can only find the o2 sensor after the convertor and i have a bad back does any one have a diagram of where the other one is hiding or is there only one.
thanks for the help.

 

It should be between the "Y" in the y-pipe (where the two sides come together) and the catalytic converter. I'll see if I can dig up a schematic.

 

thanks for looking i hope you can find something.

 

This should clear things up for you:

 

oh oh it seems someone must have swapped a pipe or something because the o2 in front of the convertor doesnt exist.im going to try and look for the o2 wire it has be under there somewhere.
