3.4 No. 2 O2 Sensor (1 Wire)
When I bought the rig the engine swap had already been done. Recently I had all the emissions equipment put back on including the CAT... We replaced the No 2, 02 Sensor, which was a one wire, with a 4 wire. It passed emissions with flying colors but ran like crap. As soon as I disconected the No 2 sensor it ran great.
I've got to find another 1 wire for this thing and get it hooked back up the way it was when I bought it... Any ideas on where I can get my hands on one. Everything I'm finding are 4 wire for before the cat (No 1 sensor)... Thnx.

Not sure of your question... both O2 sensors on my '96 3.4 were of the 4 wire variety.
There is a way to make a "fake" after cat O2 sensor however.
I copied JasonD (starts on page 10 of my swap):

What I do know fore certain is... this thing does NOT want to run with that four wire in place; not the way things are wired now.
Thanks for the help...
