Those services sounds like you were at a dealership and they were fishing for money. Not necessary if the vehicle is running nad driving fine. I wait to do the PS flush around 80K., Use top tier fuel and no need to do the fuel injection service, and throttle body can be cleaned of carbon when there is idle issues, and at 17K miles I suspect yours is clean.

Agreed. Usually, a PS flush isn't necessary unless the system has been contaminated or the fluid is worn out - 80K is about right. Fuel injection service - not needed - RARELY needed. Throttle Body Service/Cleaning is seldom necessary and usually only after a major service with a lot of miles accumulated. The Idea of cleaning the Throttle Body is to improve idle quality. Keep the Oil changed and the fuel fresh - check the quality of your antifreeze.
