Hooked up the scanner and noticed that the O2 sensors voltage read differently. This could be due to an issue with either bank. I would expect (not knowing any better) that the voltages for each O2 sensor would be relatively close to each other. These are the sensors that came off the donor vehicle with the engine.
I've felt a drop in performance over the past month, so i went ahead and ordered some replacement NTK O2 sensors to install. I'll update with a pic after the install.
I did notice a 2005 LM7 with 140k miles (no harness or front accessories) on FB for $400. I plan to go ahead and get it and rebuild pending price of parts.
[Update/thought] It may be because I think I've got a small exhaust leak under the drivers side cab area. May have some play with the readings.
