0411 swapped o2 sensor issues
0411 swapped o2 sensor issues Posted in pcm diagnostics but can't be ruled out to be some physical problem as well
1998 Z28 that was swapped over to an 0411 pcm (harness repinned) and the motor was swapped from the og 5.7 to a 6.0. I've had the car running in open loop ever since because the o2s are essentially doing the exact opposite of each other. Under moderate acceleration bank 1 pulls a -40 or so fuel trim and bank 2 adds 30+. As you can imagine the car runs like pure **** while running on the o2s. I've tried 4 different sensors in each header with no difference at all. I've tested for continuity for each O2 sensor several times as well at the PCM pins and they check out. I'm lost. What a pain in the ***...
