What damage could be done if your throttle body needs replaced?

Thank you for replying . The wrench light is on but there was a TSB #367571-Electrical System, 367572-Digital Instrument Panel, that mention the throttle body, and 359600 Power Train. I am experiencing intermittent loss of RPMs/lack of acceleration. I have 31,000 miles on my fusion. Warranty runs out December 12, 2014 or 36,000 miles. I ask Family Ford if they could update the software in the transmission control module and the power Truman control module.Sure, he said, For $81 + tax. Please advise

IF the software update is related to the throttle body problem(TSB-NOT warranty) , then I would do that first and see if that fixes it.Could be an input or signal misinterpretation problem , rather than a physical problem with T-body.

Thank-You. Totally unrated, am I entitled to get a copy of the Ford Tire Invoice that was billed by Michelin. Michelin tires are on my fusion. I'm not sure, even after reading the information about pro rated tires. Please advise
