Chevy 2500HD With A Bizarre Running Issue

In this video I have a look at a customers 2001 Chevy 2500HD with the big 6-oh and the customer states it runs very poorly as soon as it warms up. A little bit of time looking at some running data we soon discover a huge problem in the fuel trims and notice the O2 sensors are not working like they should. Sounds easy enough right? -Enjoy!
