See FAQ on throttle body cleaning. If it has not been done, you be surprised at the difference it can make (unless another problem). It's a little or no cost preventative and diagnostic measure. Also check FAQ on air intake gasket leaks (another inexpensive part).
I have never cleaned my injectors on my 740 (240,000 miles) or 940 (220,000 miles and always run high test in my 940 turbo) and both run great. I have replaced injector O'rings and cap however. This is not to say they may not need cleaning, but cleaning the TB will also help.
