I had to replace the engine block in my H3 and now by throttle body needs cleaning. on 2006 Hummer H3

I had to replace my engine block in my H3 and now 10 months later my throttle body needed cleaning - is this separate from a new engine block or part of the engine block? If part of the engine block, should I need this repair so soon or should it be covered?

Throttle body cleaning is not a repair it is maintenance and needs to be done periodically. And it might have needed it before the new block. The throttle body is not part of the block and was just transferred from the old block to the new one.
thank you.
