O2 mv SLOW TO RESPOND ON BOTH BANKS? I recently installed a 6liter in a v6 99 model truck. I had a donor truck and swapped motor, tranny, and pcm with harness. Had a check engine light that had me chasing o2 sensors. I bought 2 new GM units(117$ a pc.) and the code is still coming on. My tuner and I scanned and data logged. The o2's are working but are very slow moving. It's like watching a data log from a normal tune in slow motion.(the o2 mv's) All other parameters are in good shape.Any ideas?
