P0221 Throttle Switch B Circuit Performance
P0470 Exhaust Back Pressure Sensor Circuit Malfunction
P1139 Water in Fuel Indicator Circuit Malfunction
P3600 ?????

What are you scanning with and what is the truck doing?

imscanning with my sct livewire, the only thing I really notice with my truck is some tranny issues and when if i let off the gas peddle and then hit it again there feels like there is some play. it hits hard, same when i take cruise off going uphill. dont know if its related

With the p0221 code, you may need to replace the throttle pedal assembly.
