On the latest generation of fuel injected, engine management systems, correct diagnosis of the complete system is no longer an option, it's a requirement.
The fuel injectors and their individual performance are now one of the major components to be considered when diagnostically analyzing any system for "combustion related" problems, especially if problem is related to engine performance and fuel economy.
"Injector Diagnostics" is a testing & servicing program where the fuel distribution, fuel droplet formation, fuel atomization and fuel delivery, are all visually and physically checked and tested as a starting point, rather than a last resort.
As with carburetors, injectors are susceptible to fuel going off during periods of non-use. This can leave deposits inside the injector, causing it to become blocked, not only restricting fuel flow, but also operation of the injector pintle valve which could actually lead to over-fuelling as the valve cannot close quickly enough.  Whereas cleaning carbs has become quite common practice, injectors seem to have been ignored, as it is assumed they will not suffer the same problems. The fact is that they are more likely to suffer these problems as they are made to much closer tolerances.
People will often say, 'I've never had a problem with an injector.' Well, how do you know? Ever put a power commander on a bike and cannot get as good results as you did on the same model last week?  Problems may not manifest themselves as an obvious misfire or poor running.
The fact is that Injector servicing is needed and it works, which is why this system is approved worldwide by Robert Bosch and Delphi Automotive.
