Hope this post is appropriate for this forum. Have any of you dug into the PCM and looked at the sensor inputs? I suspect the bank 1 O2 sensor input on my '98 LS1 PCU is bad. The car is my daily driver so I haven't gotten the PCM out and done any circuit tracing on it yet. I was thinking if the sensor inputs were discrete components I could take those from the unuse bank 2 rear sensor input for replacement parts or do some wire mods and use the rear bank 2 circuit. I would appreciate any info before I start digging around.
