What, exactly, is "Throttle body Service? Same question re "Induction Service"; each for a estimated$120 service charge. Do I really need these items done at this time, with the car showing no particular symptoms?

A throttle body service is basically cleaning the passageway between the air intake and the engine. Gunk builds up around the air intake butterfly and needs to be cleaned periodically. $120 seems a bit expensive, maybe you could shop around a little. It is not difficult to remove the intake boot and clean.
