An injector cleaning is different than cleaning the throttle body. The injector cleaning will use a pressurized system to de-gunk your fuel injectors; where the throttle body cleaning will degrease the throttle body. The injector cleaning is something I would leave up to your mechanic, but the throttle body cleaning is something you can easily do yourself. You can buy a can of throttle body cleaner at any auto parts store and follow the how to guide posted on this site.
