Probably not the fuel injectors - regular fuel additives or just good
gasoline will do that. The throttle body? Maybe - they can get deposits that
will make idle get funky. However, if your idle is okay now it is an easy
DIY job with a can of carburetor cleaner. Once the idle gets bad small
passages can close off and require some real work. (My turbo Volvo gets that
way a lot from breathing its own oil mist and crankcase vapors - it doesn't
have a conventional PCV system to bypass the throttle plate.)
