I have a 2011 4.8 Sierra. Does my truck have to get reprogrammed after disconnecting, removing, and cleaning my throttle body? How often is the maf and throttle body Cleaning recommended?

Not very often. The newer models don't get as carboned up as the older models did. I've got an AMT PCV catch can so I don't introduce much oil into my intake.

 

I cleaned it last week for the 1st time in around two years and it wasn't bad at all.
