Hey guys ... I'm getting P0172 & P0175 popping up regularly on my swap. Just to recap ... 2004 5.3L truck engine with less than 5K on it now it is new basically. Put in a 1989 silverado. Oh ... and of course a Nelson Tune ... Truck runs fine with no obvious issues. Just keep getting Rich bank 1 and Rich bank 2 I've monitored the live data on the sensors and nothing seems to be wrong with the numbers I'm seeing. Just wanting some fresh ideas....

Thanks,
Brian
