2006 Hummer H3 Q&A
2006 Hummer H3 Question: I had to replace the engine block in my H3 and now by throttle body needs cleaning.
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. - Pvt-Public
